スリットとフォトダイオードの位置
高精度な測定を行うためには、Ø9 mm以下のビームを入射開口の中心に入射し、その全ビームを走査スリットで走査したのち、透過したすべての光パワーをフォトディテクタの受光面に入射させる必要があります。入射開口の前面から走査スリット、およびフォトダイオードの受光面までの距離については、下の対応するBP209の図と付属のマニュアルをご参照ください。これらの寸法をご参照いただくことにより、特に大きく発散するビームにおいて、入射光が入射瞳でクリッピングしたり、フォトディテクタの受光面よりも広がったりしないことを確認することができます。

ナイフエッジモードによる動作例。上図では、ビーム径がスリットの幅より小さい場合について示しています。

走査スリットとナイフエッジ

BP209シリーズのスリット型のビームプロファイラは、ビーム径によって走査スリットまたはナイフエッジの技術を使い分けて、ガウシアンに近い楕円形(あるいは円形)の自由空間ビームを解析します。これらの方法では、ビームの断面全体を2本のスリットで交互に走査します。1本目のスリットはビームのX軸、2本目はY軸に沿って走査します。X軸とY軸はお客様が定義しますが、多くの場合は楕円の長軸と短軸に対応させています。スリットを透過した光はフォトディテクタに入射します。光強度は、スリットの位置を参照しつつ、スリットがビームを横断的に走査して測定されます。

走査スリットモードは、ビーム径がスリット幅に対して少なくとも4倍以上ある場合に適しています。このモードでは、ビームとスリットが重なるとスリット幅と同じ幅だけのビームが透過します。スリットがビームを横断して走査すると、透過したビームの光強度がフォトディテクタで測定されます。ビーム径がスリット幅より小さい場合にはナイフエッジモードを使用します。ナイフエッジモードでは、走査スリットはビームを部分的(0~100%)に透過させます。走査スリットがビームと重なり始めると少量のビームが透過し、その後透過するビーム量は増え、最後は全てのビームが透過します。スリットとビームが重なる量、つまり透過光の強度は、スリットがさらにビームを横断して走査していくうちに減少して再びゼロになります。

これらの測定結果を用いて、X軸とY軸に沿ったビームの強度プロファイルを求めます。これらのデータを使用すれば、各軸に沿ったピークパワーとビームの重心位置、そしてビーム径と楕円率が分かります。ビームがガウシアンに近いプロファイルを持つことを仮定することで、測定されたX軸とY軸のビームプロファイルを使用してビーム断面全体の強度プロファイルを再構成し、結果を2次元または3次元のフォーマットでプロットすることも可能になります。

BP209シリーズビームプロファイラの動作概要

Drawing of Laser Beam profiler
BP209シリーズの測定ヘッドの内部は回転ドラムになっており、回転軸は手動のノブで調整できます。ドラムが回転すると、ドラム内のスリットはビームをX軸およびY軸方向に沿って走査し、透過光の強度は内蔵のフォトディテクタによって検出されます。

ソフトウェアBeam
当社のソフトウェアBeamは、ビームプロファイラおよび関連するM2測定システムの制御と測定データの収集のために開発されました。「ソフトウェア」タブからダウンロードが可能です。ソフトウェアにはGUIが付属しており、アクティブなスリットペアの選択、走査モード、利得、平均化モード、走査速度など、走査および測定に関する詳細な設定が可能です。Xプロファイル、Yプロファイル、2次元再構成、3次元プロファイル、位置の時間変化、光パワーの時間変化、計算結果などのディスプレイウィンドウについては、その構成や表示を自由に調整することできます。このソフトウェアはM2ビーム品質やビームの収束/拡散の測定が可能なほか、2本の異なるレーザービームを重ねて光ビームパラメータのチューニング作業を支援するツールも組み込まれています。ファイルに保存する測定データと計算結果を選択し、長期間の測定中に得られるデータを順次保存するオプションを有効に活用してください。ソフトウェアの紹介と代表的な表示画面については「ユーザーインターフェイス」タブでご覧いただけます。 ソフトウェアの機能についての詳細はマニュアルをご覧ください。

5 µmまたは25 µm幅のスリットによる測定
右の図は入射開口部とスリットの入った回転ドラムを含む測定ヘッドの構造です。ビームは測定ヘッドの前面に対して垂直に入り、Ø9 mmの入射開口部から回転ドラムに入射します。ドラム内のスリットは間隔をあけて配置されており、どのスリットも入射開口部の全幅をカバーするだけの幅があります。ドラム内には2組のスリットのペアがあり、どちらのペアも回転軸に対して1本が+45°、もう1本が-45°に設定されています。1組のスリット幅は5 µm、もう1組のスリット幅は25 µmです。それぞれの測定ヘッドにある2種類のスリット幅と2種類の動作モードにより、幅広いビーム径とパワーに対するプロファイリングが可能になっています。

ビーム径が20 µmまたはそれ以下の場合は25 µmスリットを使用して、ナイフエッジモードで操作してください。最小2.5 µmまでのビーム径については、この方法で測定が可能です。

走査スリットモードはビーム径が20 µm~9 mmのビーム測定に対してご使用いただけます。原則として、測定にはビーム径の1/4以下の幅のスリットを選択してください。両方のスリット幅がこの条件を満たす場合は、走査スリットの選択はビームパワーや用途の要求条件などに依存することになります。

広いパワー範囲でのビーム測定
走査スリット型ビームプロファイラが対応できる最大パワーならびに最小パワーは、1/e2ビーム径の関数として右のグラフにプロットされています。20 µmにおける黒の縦線は、ナイフエッジモードと走査スリットモードの切り替えをしなければならないビーム径を示しています。走査スリットモードにおいては、ビームパワーの最大リミット値はスリット幅5 µmで動作させたときに許容される最大パワーに対応します。5 µmスリットでは25 µmスリットよりも透過させるビーム量が少ないため、大きなパワーのビームを測定することができます。走査スリットモードにおけるビームパワーの最小リミット値は、ビーム径が約20 µm~100 µmの時は5 µmスリット、ビーム径がそれよりも大きい時は25 µmスリットを使用するとして求めています。スリットを100 µmで切り替えることにより、フォトディテクタに到達するビーム量を最大化しながら、一方ではスリット幅とビームサイズの適切な比も維持します。

以下に説明するように、ビームプロファイラを全パワーの測定に使用する場合は、これらのリミット値よりも小さな最大リミット値や大きな最小リミット値が適用される場合があります(下記参照)。 全パワーの測定値が適切なリミット値を外れる場合、ステータスボックス内にエラーメッセージが表示されます。しかしスリットを透過する光のパワーが図にプロットされたリミット内に納まるのであれば、スリットを使用したビーム形状の測定を実施することは可能です。

全パワーの測定(パワーメータの読み値)
回転ドラムには、2組のスリットのほかにNDフィルタを取り付けた開口部があります。ドラムの1回転ごとに全ビームがこの開口を通り、NDフィルタによって減衰された光の全強度がフォトディテクタによって測定されます。この全パワーの測定値はビームプロファイル測定の基準値として使用されますが、その時間経過のプロット図をGUIウィンドウに表示させることも可能です。全パワーの測定値は感度の典型的な波長依存特性により補正されていますが、校正された値ではありません。光パワーの絶対値を測定できるように、ソフトウェアを使用して対象波長における校正値を登録することもできます。

全パワーの測定を実行できるビームパワーの最大値と最小値が、上のプロット図のリミット値に届かない場合があります。グラフ内のリミット値はナイフエッジモードおよび走査スリットモードでの動作用として求められています。 走査スリットモードではビームパワーの一部がフォトディテクタに届きますが、ナイフエッジモードでは減衰されていない≤Ø20 µmの全ビームがフォトディテクタに届きます。 全パワーの測定時にフォトディテクタに到達する減衰された全ビームのパワーは、光が走査スリットを通過する場合に比べて、より小さな最大値とより大きな最小値の間になければならない場合があります。

BP209 Profiler with Rotation Mount

前面のレーザ刻印はノブが垂直方向にあるときのX軸とY軸の方向を示しており、ノブを回転させたときの軸方向の目安にご使用いただけます。

走査軸方向(X、Y)の選択
測定ヘッドの上部にあるノブ(右の写真参照)を動かす(手動)ことで、ドラムの回転軸を±60°の範囲で調整することができます。このドラムの回転軸の調整で、ビーム断面に対するXとYの走査軸の方向が変わります。これによりお客様が定義する走査軸でのビームプロファイル測定が可能となり、また走査軸の方向を変えた測定データを連続して取得することができます。ドラムは測定ヘッドの内側にあり、ノブを回しても測定ヘッドは回転しません。

この機能は入射ビームの断面が楕円形の場合に特に重要です。実際の楕円率を測定するためには、走査軸をビームの長軸と短軸にアライメントさせなければならないからです。楕円率測定のための最も正確なアライメントを実現するには、ソフトウェアでプロットされるX方向およびY方向の強度プロファイルを見ながらノブを回してください。プロファイルの幅が一方の軸で最小値、もう一方の軸で最大値となっている場合、最適な回転角度になっています。

パルスレーザービームのビームプロファイル測定
BP209シリーズは、繰返し周波数が10 Hzを超えるパルスレーザービームのビームプロファイル測定にも使用することができます。ただし、シングルショットの測定が必要な用途には、当社のカメラ型ビームプロファイラをお勧めします。

繰返し周波数が100 MHzでパルス幅が100 fsよりも小さいフェムト秒レーザの場合のように、パルスの繰返し周波数が高くパルス幅が短い場合には、CW信号とパルス信号の解析には違いがありません。これはフォトダイオードの電流増幅器の帯域幅が制限されているためで、個々のパルスが分解できず、代わりに入射パルス列を効果的に平均化してCW信号を生成します。

パルスレートが約50 kHzまたはそれ以下の場合、適切に測定するにはソフトウェアで走査速度を設定してください。走査速度の設定可能範囲は1.5 Hz~20 Hzとなっているため、走査速度をパルスレートと同じ速さに設定することは多くの場合はできません。走査速度(周波数)の整数倍とパルスレートが若干異なるように設定し、Hold Maximum機能をEnableにして測定を行ってください。走査が1セット実施されると、ソフトウェアは走査中に測定されたピーク強度値を蓄積して平均化します。パルスレートが1回の走査で1つ以上のパルスを測定するのに十分な速度を有する場合、ソフトウェアは測定パルスのセグメントごとのピーク強度値を蓄積して平均化します。出力されるビームプロファイルは最終的に平均化された1セット分の測定値となります。走査速度(周波数)の整数倍とパルスレートが若干異なるように設定することで、1回の走査ごとにビームプロファイルの異なる部分の測定ができ、1セットの走査でビームプロファイルの全セグメントの測定値が得られます。

Dear Mr. Scharl, thank you for your feedback. We do not have any maximum power/energy estimate for pulsed lasers. For use with pulsed lasers, we recommend that you set your beam profiler to the maximum integration time. Slowly increase the power of your laser, until the signal reaches approx. 50% of the intensity as shown in the profile window on the Beam software package. Multiply this power by a factor of 10. And this should be the safe upper limit of the mean pulse power for the beam profiler.

Hello, I am facing issue from BP209-VIS/M. The beam profiler worked well untill last week but suddenly, it doesn't work. RDY LED does not light up, SW doesn't recognize beam profiler at USB window, Firmware update software also does not read the profiler. I have used another USB cable, re-install the SW but still doesn't work. Would there be anything I can try? Thanks.

Hello, We used BP209-VIS/M and M2MS to measure the beam characteristics of the laser pulse focusing spot (Laser: 532nm,100Hz, 10ns). We would like to ask the following two questions: 1. Can BP209-VIS/M synchronize with the frequency of the laser through external trigger mode? 2. What is the range of beam fluence of pulsed laser that BP209-VIS/M can tolerate?Because when I keep increasing the laser fluence, it always indicates that the energy is low. Thanks.
dpossin  (posted 2024-02-07 08:59:15.0)
Dear Yao, Thank you for your feedback. 1.) The BP209-VIS does not provide an external trigger input. However pulsed lasers can be measured through the max hold function. There the software accumulates the peak intensities over a number of subsequent pulses leading to an averaged profile. Additionally the bandwidth needs to be adapted to the pulses and beam diameter. 2.) The max beam power is given for CW sources only. As a rule of thumb I would recommend to set the gain to max and attenuate the laser such that peak power is just below the max cw power we give according to the beam diameter. If there is no signal, the laser power should be gradually increased until a signal can be seen.

Hello, I wanted to share an issue I encountered with the Thorlabs Beam software version 9.0. When using the camera BC106N-VIS/M, I am not able to save the 2D image of the beam. Using any format (bmp/jpg/png/tiff), all that is saved is black rectangle. The 3D image of the beam can be saved. The previous version, 8.2, works with no problems for me with all image formats, so I use that one instead. Perhaps this is just the problem on my laptop, but maybe it is more general... Best regards, Karolina Stefańska

Greetings, Does the Extended InGaAs detector have a non-zero response below 800nm? The nomina is 900nm but the graph shows it going down to about 800nm, but can it be pushed even lower to say 650nm at the cost of SNR/integration time?

同製品を使用させて頂いております。 20um以下のスポット光を測定したいと考えております。 説明書ではナイフエッジモードの使用が推奨されていると思うのですが、ナイフエッジモードでは Base Line Modeをマニュアルに設定するよう記載があります(英語取説 p75)。マニュアル設定にした場合、x/yスリットごとの補正値はどのように決める必要がありますでしょうか? スポット光の構成 [波長905nm, CW光源, 光量250uW程度]

Dear customer, thank you for your feedback. Indeed, it is recommended to use the knife edge mode to measure small beams <20µm and the baseline correction has to be adjusted, if it is not set correctly. In the software you can see the baseline in the X and Y profile. According to that you can adjust the baseline correction. I will contact you directly to discuss this further with you.

Hello, We are trying to use the BP209-VIS/M to track the location of one continuous wave laser beam as it is displaced laterally over a small distance (~several microns). We notice that the calculated centroid and peak positions of the beam fluctuate too much to take the displacement measurement, and are wondering if this fluctuation is intrinsic to the beam profiler. Furthermore, we noticed that when we displace the beam quickly, the calculated positions do not seem to update as expected, even though the image in the 2D reconstruction has moved by tens of microns. We'd greatly appreciate any insight on these issues!

Thank you for your feedback! The C example takes ten measurements and outputs the peak position and the centroid position of each.

Hi, we are having a problem with our slit beam profiler: a round beam (single mode fibre output) is measured (gauss width) to be elliptical when using the 5 um slits whereas it is round when using the 25 um slits. Power and beam size are adequate (10 mW, e.g. 700 um beam width). With the 5 um slits the beam is 5 % smaller in the one direction and 5 % bigger in the other compared to the 25 um slits. roating the beam profiler does not change the measurement. Best regards
wskopalik  (posted 2022-12-15 04:41:51.0)
Thank you for your feedback! If rotating the beam profiler does not change the elliptical beam shape of the measured profile and the 25 µm slits show the expected round beam, then there is most likely an issue with the 5 µm slits.

Hello, I have a question regarding your BP209-VIS scanning slit profiler. How well does it operate with nanosecond and picosecond pulsed lasers? You mention a minimum rep rate, does it still operate with these pulsewidths in the 50 kHz+ rep. rate regime? Kevan
MKiess  (posted 2020-10-20 10:17:10.0)
Dear Kevan, thank you very much for your inquiry. In general, camera beam profilers are better suited for measuring pulsed laser sources, but you can also use the BP209 for nanosecond pulses at fast repetition rates. At 50kHz, the scan rates have to be adjusted in the software to get the best results. To do this, you have to set the scan rate so that an integer multiple of the scan rate is slightly different than the pulse rate. Because, setting the integer multiple of the scan rate to differ slightly from the pulse rate ensures that each scan measures a different portion of the beam profile; the set of scans should include measurements of all segments of the beam profile.

I am intersted in a beam profiler at focus for a 7um spot at 1340nm and 0.5-10kHz repetition rate. Could you give advice whether this would be suitable.
MKiess  (posted 2019-03-12 04:44:40.0)
This is a response from Michael at Thorlabs. Thank you for the inquiry. With the BP209 series the beam profile of a beam with a diameter of 7µm and a wavelength of 1340nm can be measured. Pulsed laser beams can be measured at repetition rates greater than 10Hz. If the pulse frequencies are in the range of 50 kHz and less, the beam profiler does not analyze the beam as a CW signal, as is the case with very fast frequencies. Therefore, the scan rate settings must be configured in the software to achieve optimal measurements. This is done by setting the sampling rate so that an integer multiple of the sampling rate is slightly different from the pulse rate. When the Hold Maximum function is enabled, series of scans are performed and the software accumulates and averages the measured peak intensities in the scan set. I will contact you directly to discuss detailed software settings and whether the better choice for this application would be a Thorlabs' Camera Beam Profiler.

At the time our Scanning Slit Beam Profilers are covering operating wavelength ranges of 200 - 1100 nm (BP209-VIS) or 900 - 1700 nm (BP209-IR). For measuring beams at 200-1700nm both the BP209-VIS and the BP209-IR have to be used. We will contact you directly to provide assistance.

I have a question about the optical measurement plane. In your CAD drawing it is 2.1mm inside the device, but I cannot tell if that is measured from the front or rear surface. We are producing a 4 micron diameter spot size using an objective lens. The working distance is pretty small, so I would like to know if it will be possible to position the lens close enough to the device to place the focal point at the plane of beam measurement. Also, will the device work if it is not placed upright? Our beam propagation is in the upwards vertical direction, so we would have to lay the BP209 face down on some kind of fixturing to allow the beam to be captured.
tschalk  (posted 2015-05-18 09:53:48.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The measurement plane is located 2,1mm inside the device measured from the front surface. For beam diameters below 20µm the knife edge mode has to be used. Detailed information about that mode can be found in the manual at section 4.3.8 Knife Edge Mode. The device can also be used in a horizontal position but you have to take care that you dont affect the rotating drum in order to avoid a damage of slits. I will contact you directly with more detailed information.

Is it possible to get a trigger out signal, or real time photodetector reading for synchronization of the measurements to other events?
shallwig  (posted 2015-04-13 03:23:40.0)
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. At the moment it is unfortunately not possible to offer this device with a trigger output. We cannot offer a software trigger as a very precise determination of the slit position is not possible with our software. From the beam profilers housing design there is not enough space for integrating a hardware trigger. The built in encoders only have a limited accuracy in position determination thus the internal feedback circuit readjusts the rotation speed all the time. Therefore it is difficult to get out a trigger signal very precisely each time the slit crosses the beam. We have contacted you directly to discuss your application in more detail and to check if there is a possibility to implement a trigger in the future.

This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. Because of the low rep rate of your laser source a slit beam profiler is not suited for your application. We can offer a CCD camera beam profiler BC106N-VIS which is also able to determine the profile of a single pulse. Please note that damage threshold data is currently not available for our beam profilers. For use with pulsed lasers, we recommend the following procedure as a guideline for determining a safe upper limit: Set the beam profiler to the maximum integration time (i.e., set the exposure to 1 s). Slowly increase the power until your signal reaches approximately 50% of the intensity as shown in the Profile window of the Beam software package. Multiply this power by a factor of 10. This is the safe upper limit of the mean pulse power for the beam profiler. I will contact you directly to discuss your application.

Our lab has purchased the following laser beam profiler from Thorlabs: BP104-IR We are trying to use this item to profile a laser beam with a wavelength of 1550 nm. The unit we are using to produce the laser beam is an amplifier from NP Photonics, which enables us to output powers ranging from 40 mW to about 5 W. I have been attempting to use the BP104-IR to perform this profiling. However it seems that the beam computer software 'crashes' when I attempt to use the BP104-IR for powers greater than 65 mW. The profiler does work for powers below 65 mW, however if we exceed this threshold, the following error occurs: "The Beam Profiler device has been removed. Please reconnect the Beam Profiler, refresh the device and select the device again" I have been unable to resolve this issue by consulting the operation manual, and there fore am seeking technical support and advise to overcome this issue.

A response from Julien at Thorlabs: this type of measurement is in principle possible but there will be several points to carefully consider in order to ensure the best possible measurement accuracy. For instance, you will need to ensure that the beam power is strongly reduced to avoid damage. Also, due to the large tuning range of this system, you will only be able to measure a portion of the spectral range with a given beam profiler. Finally, the fact that the laser is pulsed will tend to increase the measurement time for a given profile. We would be happy to further discuss all those points and help you in your choice of beam profiler. Please feel free to contact us any time at techsupport@thorlabs.com

1). How should I determine the allowed input power in case of pulsed lasers? We use 1.06 µm 45-100 kHz source with 150-200 ns pulse duration, so the peak power is 50-150 times higher then the average power. The beam diameter is usually 600 µm. Should I keep the peak power below 1 W, or it is safe to use any source with average power less then 1 W ? Is it safe to refer to the profiler’s readings when analyzing the usable power level? 2). How should I use the power ranges diagram in case of extremely elliptic beam, e.g. 8:1? Which upper power limit should I take – the one that corresponds to the minimum width, or the one that corresponds to the maximum width? Thank you in advance.

Useful product for its price but the Rotation Mount is not firm enough. The Scanning Head can move too much inside the Rotation Mount. We have had to set our rotational position and then glue the Head in the Mount, which is not optimal but works. Otherwise values vary by too much for beams that diverge quickly.

No, it should not, if the BP10x device settings were made correct. Please explain more detailed, why you are asking that. 2)No, in the SW you can observe either 2D profiles (in real time) or you can watch the virtual (calculated) 3D profile - a slit scanning beam profiler cannot deliver a genuine 3D profile, becaúse the slits are scanning the beam under +45° and -45° angle simultaneously.

A response from Juergen from Thorlabs to c.j.lee: The BP10X beam profilers are based on a rotating drum with scanning slits. The source of electrical signal is a photodiode, locate behind the slits inside the drum. As for this, X and Y 2D profiles are real time profiles, as they represent the photodiode current vs. time. The X and Y scans can be saved, which make sense of course only for Gaussian or close to Gaussian beam profiles. A beam profile in 3D in this case can be calculated only, its not a real picture, but just a virtual image - this is the reason why 3D profile cannot be exported as a number or array of data: There is only 1 value changing in time, and this time is formed by human eye to a consistent picture while its actually only a sequence of dots. Analogy: old CRT TV images... "quite messy beams" is clearly NOT a suitable application for any scanning slit beam profiler (not only made by Thorlabs). We offer a camera beam profiler, where the beam profile is represented in a real 3D picture, based on a CCD camera - pixel coordinate and its intensity. The item # is BC106-VIS or -UV. Unfortunately, there is no IR version available due to a lack of IR sensitive CCD image sensors (Si is becoming transparent above 1000nm) So, in order to resolve your issue, Id like to ask you about details on your laser: - type of laser - CW or pulsed? - wavelength - power? - beam diameter? - expected beam shape? - what beam parameters you want to characterize?

We have already purchased the IR version of the beam profiler, but the software has disappointed us somewhat. It appears to be impossible to extract a complete image as an array of values (or as an image, for that matter) from the program. Instead, the program produces a screen shot of the window. I have read the manual and found nothing that looks appropriate. That is, to put it mildly, absolutely pathetic for any use other than generating publicity for Thorlabs. It is especially useless if you are dealing with beams that are quite messy, because you cannot adequately control how the beam parameters are analyzed and the x-y center cuts might not be appropriate. Is there someway to extract this data? Other than to cut out the appropriate part of each screen shot and run them through an image analysis program?

A reply from Jens at Thorlabs: the issue here is that your repetition rate is in the same range as the drum scanning frequency. The example in the manual describes repetition rates of the light srouce in the kHz range. With that the drum will see several pulses while it is scanning which will allow it to calculate the beam shape. In your case a CCD based profiler will be the better option. I will contact you directly to discuss next steps and ask our development to add more details regarding the lower limit repition rate to the manual.

Please, advise, how to synchronize BP109-UV with 10 Hz 18 ns laser. Reading users manual doesnt help, as its imposible to reach necessary parameters using provided software.

A response from Tyler at Thorlabs to lok.eg: The beam profiler can be used to measure 60 fs pulses for repetition rates above 10 Hz. The damage threshold is dependent on the beam diameter. Because of the short pulse duration, the amplifier will only be sensitive to the average power of the beam, which should be kept below 1 W. Please see the specs tab for how the operating power range is dependent on the beam diameter. Thank you for considering the BP109-UV beam expander. As an alternative you may wish to consider our camera based beam profiler (BC106-UV).

Is it possible to use BP109-UV with 60 fs pulses? (10 Hz or single pulse; 266, 400, 800 nm; 4 mm) Whats the highest power allowed then?
