### レーザによる損傷閾値について

このチュートリアルでは、レーザ損傷閾値がどのように測定され、使用する用途に適切な光学素子の決定にその値をどのようにご利用いただけるかを総括しています。お客様のアプリケーションにおいて、光学素子を選択する際、光学素子のレーザによる損傷閾値(Laser Induced Damage Threshold ：LIDT)を知ることが重要です。光学素子のLIDTはお客様が使用するレーザの種類に大きく依存します。連続(CW)レーザは、通常、吸収(コーティングまたは基板における)によって発生する熱によって損傷を引き起こします。一方、パルスレーザは熱的損傷が起こる前に、光学素子の格子構造から電子が引き剥がされることによって損傷を受けます。ここで示すガイドラインは、室温で新品の光学素子を前提としています(つまり、スクラッチ&ディグ仕様内、表面の汚染がないなど)。光学素子の表面に塵などの粒子が付くと、低い閾値で損傷を受ける可能性があります。そのため、光学素子の表面をきれいで埃のない状態に保つことをお勧めします。光学素子のクリーニングについては「光学素子クリーニングチュートリアル」をご参照ください。

### CWレーザと長パルスレーザ

パルス長が1 nsと1 µs の間のときは、損傷は吸収、もしくは絶縁破壊のどちらかで発生していると考えることができます(CWとパルスのLIDT両方を調べなければなりません)。吸収は光学素子の固有特性によるものか、表面の不均一性によるものかのどちらかによって起こります。従って、LIDTは製造元の仕様以上の表面の質を有する光学素子にのみ有効です。多くの光学素子は、ハイパワーCWレーザで扱うことができる一方、アクロマティック複レンズのような接合レンズやNDフィルタのような高吸収光学素子は低いCWレーザ損傷閾値になる傾向にあります。このような低い損傷閾値は接着剤や金属コーティングにおける吸収や散乱によるものです。

ある光学素子の固有のCWレーザの損傷閾値を使う場合には、以下のことを知る必要があります。

1. レーザの波長
2. ビーム径(1/e2)
3. ビームのおおよその強度プロファイル(ガウシアン型など)
4. レーザのパワー密度(トータルパワーをビームの強度が1/e2の範囲の面積で割ったもの)

ビームのパワー密度はW/cmの単位で計算します。この条件下では、出力密度はスポットサイズとは無関係になります。つまり、スポットサイズの変化に合わせてLIDTを計算し直す必要がありません(右グラフ参照)。平均線形パワー密度は、下の計算式で算出できます。

ここでは、ビーム強度プロファイルは一定であると仮定しています。次に、ビームがホットスポット、または他の不均一な強度プロファイルの場合を考慮して、おおよその最大パワー密度を計算する必要があります。ご参考までに、ガウシアンビームのときはビームの強度が1/e2の2倍のパワー密度を有します(右下図参照)。

この目安は一般的な傾向ですが、LIDTと波長の関係を定量的に示すものではありません。例えば、CW用途では、損傷はコーティングや基板の吸収によってより大きく変化し、必ずしも一般的な傾向通りとはなりません。上記の傾向はLIDT値の目安として参考にしていただけますが、LIDTの仕様波長と異なる場合には当社までお問い合わせください。パワー密度が光学素子の補正済みLIDTよりも小さい場合、この光学素子は目的の用途にご使用いただけます。

### パルスレーザ

パルス幅が10-9 sより短いパルスについては、当社の仕様のLIDT値と比較することは困難です。この超短パルスでは、多光子アバランシェ電離などのさまざまなメカニクスが損傷機構の主流になります[2]。対照的に、パルス幅が10-7 sと10-4 sの間のパルスは絶縁破壊、または熱的影響により光学素子の損傷を引き起こすと考えられます。これは、光学素子がお客様の用途に適しているかどうかを決定するために、レーザービームに対してCWとパルス両方による損傷閾値を参照しなくてはならないということです。

 Pulse Duration Damage Mechanism Relevant Damage Specification t ＜ 10-9 s 10-9 ＜ t ＜ 10-7 s 10-7 ＜ t ＜ 10-4 s t ＞ 10-4 s Avalanche Ionization Dielectric Breakdown Dielectric Breakdown or Thermal Thermal N/A Pulsed Pulsed and CW CW

お客様のパルスレーザに対してLIDTを比較する際は、以下のことを確認いただくことが重要です。

エネルギ密度におけるLIDTに対するパルス長＆スポットサイズ。短パルスでは、エネルギ密度はスポットサイズにかかわらず一定です。このグラフの出典は[1]です。

1. レーザの波長
2. ビームのエネルギ密度(トータルエネルギをビームの強度が1/e2の範囲の面積で割ったもの)
3. レーザのパルス幅
4. パルスの繰返周波数(prf)
5. 実際に使用するビーム径(1/e2 )
6. ビームのおおよその強度プロファイル(ガウシアン型など)

ビームのエネルギ密度はJ/cm2の単位で計算します。右のグラフは、短パルス光源には、エネルギ密度が適した測定量であることを示しています。この条件下では、エネルギ密度はスポットサイズとは無関係になります。つまり、スポットサイズの変化に合わせてLIDTを計算し直す必要がありません。ここでは、ビーム強度プロファイルは一定であると仮定しています。ここで、ビームがホットスポット、または他の不均一な強度プロファイルの場合を考慮して、おおよその最大パワー密度を計算する必要があります。ご参考までに、ガウシアンビームのときは一般にビームの強度が1/e2のときの2倍のパワー密度を有します。

ビーム径は損傷閾値を比較する時にも重要です。LIDTがJ/cm2の単位で表される場合、スポットサイズとは無関係になりますが、ビームサイズが大きい場合、LIDTの不一致を引き起こす原因でもある不具合が、より明らかになる傾向があります[4]。ここで示されているデータでは、LIDTの測定には＜1 mmのビーム径が用いられています。ビーム径が5 mmよりも大きい場合、前述のようにビームのサイズが大きいほど不具合の影響が大きくなるため、LIDT (J/cm2)はビーム径とは無関係にはなりません。

お客様のレーザのパルス幅をもとに、光学素子の補正されたLIDTを計算するのにこの計算式を使います。お客様の最大エネルギ密度が、この補正したエネルギ密度よりも小さい場合、その光学素子はお客様の用途でご使用いただけます。ご注意いただきたい点は、10-9 s と10-7 sの間のパルスにのみこの計算が使えることです。パルス幅が10-7 sと10-4 sの間の場合には、CWのLIDTも調べなければなりません。

レーザーシステムが光学素子に損傷を引き起こすかどうか判断するプロセスを説明するために、レーザによって引き起こされる損傷閾値(LIDT)の計算例をいくつかご紹介します。同様の計算を実行したい場合には、右のボタンをクリックしてください。計算ができるスプレッドシートをダウンロードいただけます。ご使用の際には光学素子のLIDTの値と、レーザーシステムの関連パラメータを緑の枠内に入力してください。スプレッドシートでCWならびにパルスの線形パワー密度、ならびにパルスのエネルギ密度を計算できます。これらの値はスケーリング則に基づいて、光学素子のLIDTの調整スケール値を計算するのに用いられます。計算式はガウシアンビームのプロファイルを想定しているため、ほかのビーム形状(均一ビームなど)には補正係数を導入する必要があります。 LIDTのスケーリング則は経験則に基づいていますので、確度は保証されません。なお、光学素子やコーティングに吸収があると、スペクトル領域によってLIDTが著しく低くなる場合があります。LIDTはパルス幅が1ナノ秒(ns)未満の超短パルスには有効ではありません。

ガウシアンビームの最大強度は均一ビームの約2倍です。

CWレーザの例

しかし、ガウシアンビームの最大パワー密度は均一ビームの約2倍です(右のグラフ参照)。従って、システムのより正確な最大線形パワー密度は1 W/cmとなります。

アクロマティック複レンズAC127-030-CのCW LIDTは、1550 nmでテストされて350 W/cmとされています。CWの損傷閾値は通常レーザ光源の波長に直接スケーリングするため、LIDTの調整値は以下のように求められます。

LIDTの調整値は350 W/cm x (1319 nm / 1550 nm) = 298 W/cmと得られ、計算したレーザーシステムのパワー密度よりも大幅に高いため、この複レンズをこの用途に使用しても安全です。

ナノ秒パルスレーザの例:パルス幅が異なる場合のスケーリング

このビームのエネルギ密度を、広帯域誘電体ミラーBB1-E01のLIDT 1 J/cm2、そしてNd:YAGレーザーラインミラーNB1-K08のLIDT 3.5 J/cm2と比較します。LIDTの値は両方とも、波長355 nm、パルス幅10 ns、繰返し周波数10 Hzのレーザで計測しました。従って、より短いパルス幅に対する調整を行う必要があります。 1つ前のタブで説明したようにナノ秒パルスシステムのLIDTは、パルス幅の平方根にスケーリングします:

この調整係数により広帯域誘電体ミラーBB1-E01のLIDTは0.45 J/cm2に、Nd:YAGレーザーラインミラーのLIDTは1.6 J/cm2になり、これらをビームの最大エネルギ密度0.7 J/cm2と比較します。広帯域ミラーはレーザによって損傷を受ける可能性があり、より特化されたレーザーラインミラーがこのシステムには適していることが分かります。

ナノ秒パルスレーザの例:波長が異なる場合のスケーリング

スケーリングによりLIDTの調整値は反射型フィルタでは0.08 J/cm2、吸収型フィルタでは14 J/cm2となります。このケースでは吸収型フィルタが光学損傷を防ぐには適した選択肢となります。

マイクロ秒パルスレーザの例
パルス幅1 µs、パルスエネルギ150 µJ、繰返し周波数50 kHzで、結果的にデューティーサイクルが5%になるレーザーシステムについて考えてみます。このシステムはCWとパルスレーザの間の領域にあり、どちらのメカニズムでも光学素子に損傷を招く可能性があります。レーザーシステムの安全な動作のためにはCWとパルス両方のLIDTをレーザーシステムの特性と比較する必要があります。

この比較的長いパルス幅のレーザが、波長980 nm、ビーム径(1/e2)12.7 mmのガウシアンビームであった場合、線形パワー密度は5.9 W/cm、1パルスのエネルギ密度は1.2 x 10-4 J/cm2となります。これをポリマーゼロオーダ1/4波長板WPQ10E-980のLIDTと比較してみます。CW放射に対するLIDTは810 nmで5 W/cm、10 nsパルスのLIDTは810 nmで5 J/cm2です。前述同様、光学素子のCW LIDTはレーザ波長と線形にスケーリングするので、CWの調整値は980 nmで6 W/cmとなります。一方でパルスのLIDTはレーザ波長の平方根とパルス幅の平方根にスケーリングしますので、1 µsパルスの980 nmでの調整値は55 J/cm2です。光学素子のパルスのLIDTはパルスレーザのエネルギ密度よりはるかに大きいので、個々のパルスが波長板を損傷することはありません。しかしレーザの平均線形パワー密度が大きいため、高出力CWビームのように光学素子に熱的損傷を引き起こす可能性があります。

I will reach out to you directly regarding a quote for these.user  (posted 2017-06-20 09:53:56.503)Hello, In the product overview section, you write: "Light can be input into any of the polished faces to separate the s- and p-polarizations. However, for best performance, the light should enter through one of the entrance faces of the coated prism, which are indicated by a dot." However, it is unclear what is meant by "for best performance". I am sending laser light on two cascaded PBSs. On the first PBS the light is incident on the dotted prism, so the transmitted light is p-polarized with high purity. On the second PBS, the light is incident on the non-dotted prism, and ~10% of the light is reflected, despite the high purity. Is this normal behavior? Can it still be claimed that either facet can be used to separate polarizations? I am trying to combine two beams of orthogonal polarization into a single beam. In this case it is inevitable that one beam will enter the non-dotted prism. I don't want to lose 10% of the light. Can you recommend a different product? I am using 1550nm light. Thank you very much.tfrisch  (posted 2017-06-27 10:19:59.0)Hello, thank you for contacting Thorlabs. There are two different effects happening here. First, the not about optimal performance concerns the manufacturing method. At the beamsplitting interface, there is a beamsplitter coating as well as cement that holds the two halves together. They are designed such that the light should be reflected off of the coating before passing through the cement, but this is negligible in most applications. As for the 10% reflectance, that is normal. The high purity of the transmitted beam is achieved by maximizing the reflectance of the S state. This minimizes the transmission of the S state so that the transmission is almost entirely P- polarized. However, the reflected state has a significant reflectance for the P state (about 10% as you note). Please reach out to TechSupport@Thorlabs.com to further discuss your application and the sources you are looking to combine.john.kirtley  (posted 2017-05-03 18:47:06.983)Hello, I am wondering if the 420-680 nm cube will also reflect light at 785 nm. The graph shows still relatively decent beam splitting at 785 nm, so while the P polarized light is transmitted, I am wondering if the S-polarized light is reflected at 785nm. Thanks.tfrisch  (posted 2017-05-19 02:07:08.0)Hello, thank you for contacting Thorlabs. As seen on the Graphs tab, there is a significant transmission bump in the S state in the NIR. Because of this the PER will be greatly reduced. However, absorption would be low, so the non-transmitted component of the S state would be reflected, yes. I will reach out to you directly to discuss your application.kc636  (posted 2016-03-24 09:28:52.423)Do you have a beamsplitter that would work in the 1600-2200nm range? Alternatively, what is the performance of PBS124 at 1800nm?besembeson  (posted 2016-03-24 02:35:47.0)Response from Bweh at Thorlabs USA: You may want to consider the Glan-Taylor (http://www.thorlabs.us/newgrouppage9.cfm?objectgroup_id=816) or Glan-Laser (http://www.thorlabs.us/newgrouppage9.cfm?objectgroup_id=815) polarizers, whose un-coated versions can be used over a broader spectrum. The polarizing beam splitter coatings generally perform poorly outside the designed spectral range so the PBS124 will not be suitable around 1800nm.joachim.fischer  (posted 2015-01-20 09:47:30.947)Dear Thorlabs team, do you have (numerical) data for phase vs. wavelength of the reflected beam available? That would be very interesting for me. I'm especially interested in the PBS121.

What about the polarization states of two beams at the output? Thanks Yuweibesembeson  (posted 2014-10-30 05:18:07.0)Response from Bweh at Thorlabs USA: Yes you could use this as a beam combiner although we don't have test data yet for this orientation. We expect the polarization states of both beams to stay the same during and after combination. In terms of the expected output power, note that the transmission efficiency of the beamsplitter coating for the p-polarized state is >90% and the reflection efficiency for s-polarized light is >99.5%.dmahler  (posted 2014-04-07 15:07:44.713)What spec (if any) is there for the amount of wedge in the glue used to hold the two prisms together? I am measuring an optical path difference of around 10 microns for two beams entering the beamsplitter about 2mm apart, and am trying to rule out wedge in the beamsplitter. Thanks,cdaly  (posted 2014-04-09 04:19:18.0)Response from Chris at Thorlabs: We do not have a specification for the wedge angle created by the epoxied surfaced between the prisms. We do however specify a transmitted beam deviated spec to be <5armin. Depending on the deviation along with the incident angle of the beam, this could account for the observed path length difference.leaf  (posted 2014-01-21 09:50:36.73)I am looking for a PBS for both 1064 and 1550 nm wavelengths.

It seems quite high damage threshold. Is it true?tcohen  (posted 2013-11-07 03:53:53.0)Response from Tim at Thorlabs: With a focused spot diameter of 18um, the PBS053 showed no damage with an exposure duration of a minute on 20 separate sites with a power exceeding 10000 W/cm at 1064 nm, Ø0.018 mm. Although we would expect this linear power density to remain constant for an increased beam size, a larger beam is more likely to land on a damage precursor (such as a surface defect), and thus cause damage.ajh  (posted 2013-10-30 17:29:04.08)Could you give a number for the percentage of reflectivity of the AR-coatings at 632nm? In other words, how much ghost reflections does one get at 90degree incidence?tcohen  (posted 2013-11-07 03:43:35.0)Response from Tim at Thorlabs: Each outer optical surface is BBAR coated. The spec within the coating region is Ravg<0.5% at normal angle of incidence. Each surface will have this spec and so you can use this to calculate first back reflection and any ghost reflections after splitting for an approximation of ghost beams.asvaghos.a  (posted 2013-08-09 06:34:11.04)I happened to drop my PBS253 cube to ground.

The design wavelength of the PBS051 is 420nm-680nm. Even with an AR coating of 400nm-700nm, the beamsplitter coating would be out of the specified band. To change the design wavelength would involve creating a custom coating, which would include engineering costs and coating production costs. We offer N-BK7, UVFS, CAF2, ZnSe and Ge right angle prisms. I would like to discuss with you the requirements of your system to provide the best options for your application and I will contact you directly to continue this conversation.joekkrause  (posted 2012-06-28 23:39:17.0)How much would it cost for you to make a custom cube of N-SF1 with an AR coating for the 400-700 nm range?

It is difficult to produce exact damage thresholds because of the many variables involved. For CW, usually damage occurs first in the substrate. However, surface irregularities in the optic can also play a role. The intensity profile of your beam will also have an influence on a CW LIDT. As an estimate, we advise not using over 13W/cm^2 CW for this product. However, because LIDT decreases with an increase in frequency, the threshold will be lower for your lower wavelength. I have contacted you directly to find out more information on your setup.utsavdeepak.dave  (posted 2012-02-29 09:55:44.0)Hi, I would like to know the damage threshold for the PBS251 product used with blue light (464 nm, CW).bdada  (posted 2011-10-06 20:21:00.0)Response from Buki at Thorlabs: Thank you for your feedback. What you may be experiencing is the magneto optical Kerr effect - where the polarization of light changes when it interacts with magnetized media. We think the coating and not the material is what is being magnetized and causing the reflected/transmitted beams to be altered. This magnetization will change as the external magnetic field changes, explaining why the unbalance changes at the same frequency as the rotation of the magnetic field. Please contact TechSupport@thorlabs.com if you want to discuss this further.nmandal  (posted 2011-09-28 15:56:42.0)Should the intensities of the two beams coming out of the PBS change in presence of magnetic field? I balance the two beams coming out of the PBS and bring a rotating magnetic field closer to the PBS and I see that the beams are not balanced anymore and the unbalance has the same frequency as the magnetic field. I know the PBS contains SF2 which is polar, could this be the cause or something else.jjurado  (posted 2011-06-22 12:50:00.0)Response from Javier at Thorlabs to Mikhail.Levin: Thank you very much for contacting us with your request. We currently do not have information regarding the dependence of the extinction ratio upon the angle of incidence for these polarizing beamsplitters. However, as a guideline, increasing the AOI beyond +/- 2 degrees from the normal of the front surface of the PBS will most likely negatively affect the resultant extinction ratio between the s and p polarizations. I will contact you directly for further support.Mikhail.Levin  (posted 2011-06-21 16:00:08.0)Please inform about the angular sensitivity of your product Other words: show the andle( +/- N degrees) in which the extinction parameter (~30dB) is valid Customer Email: Mikhail.Levin@amo.abbott.com This customer would like to be contacted.jjurado  (posted 2011-03-18 11:14:00.0)Response from Javier at Thorlabs to drdougsnyder: Thank you for contacting us with your inquiry. Intrinsic variations in the beamsplitter coating result in different retardance values for both s and p components. For the passing beam (this would be Tp, and Rs), you can expect a retardance on the order of 0.01 waves (worst case), and 0.00 waves in the best case. For the rejected beam (Ts and Rp), the phase change can range from 0.00 to 0.125 waves.jjurado  (posted 2011-03-15 11:55:00.0)Response from Javier at Thorlabs to last poster: Thank you for submitting your inquiry.

Although is is unlikely that the AR coating on the cubes will considerably affect contrast, we can certainly offer these polarizing cubes uncoated.

Our beamsplitters are comprised of two separate prisms. We apply a dielectric coating to the hypotenuse side of one of the two prisms, and then we use cememt to bond the two prisms together.

However, these do not work as well as the PBS3, and you may receive some wavefront errors from the extraordinary ray, as this side does not have a good polish. If we can be of further assistance, please let us know.ADudley  (posted 2008-10-02 03:41:49.0)I am interested in this product, but for the visible wavelength (400-700nm).
