- コリメート型または焦点調整型レーザーモジュール
- 小型のØ8 mmまたはØ11 mmの筐体で、アライメントレーザとして利用可能
- 波長範囲405 nm～980 nmのレーザ(右の表参照)
- 4種類の635 nmレーザはHeNeレーザの代用品として使用可能
- 850 nmのコリメート型単一波長VCSELレーザーモジュールもご用意
- 円形または楕円形のビームプロファイルから選択可能
- 内蔵のフォトダイオードフィードバックを利用した定出力モード
- 電源や、電源と筐体付きのレーザーモジュール取付けキットもご用意
当社ではコリメート型および焦点調整型のレーザーモジュールをご用意しており、出力は0.85 mW～4.5 mWでラインナップしています(レーザ安全基準のクラスは2または3Rでモデルによって異なります)。各モジュールの出力ビーム形状は楕円形または円形で、それぞれ下の表に記載されています。空間シングルモード出力で、小型な円筒状の筐体に納められていることから、光学系内のアライメントレーザとしての使用に適しています。
単一周波数の用途向けに、当社のコリメート型850 nm VCSELモジュールは、単一波長で、円形のガウシアン形状のビームを出力します。狭い線幅で、側帯波を含まないスペクトルを生成しますが、合計出力値は低くなります。
すべてのCPSシリーズレーザーモジュールは、内蔵フォトダイオードからのフィードバックを利用して光出力パワーを一定に維持する、定出力モードで駆動します。しかしこれらのレーザは温度安定化されていないため、動作中の光出力が若干変動する可能性があります。
電源オプション
各モジュールの動作には5 VDC(レーザーモジュールには電源は付属しません)が必要です。当社では、下記掲載のウォールアダプタLDS5をご用意しています。CPSシリーズレーザーモジュールはアダプタLDS5の出力部分に直接接続できますが、外部電源のバッテリーパックはUSB-フォノプラグを使用する必要があります。
また、お客様がお持ちの電源をモジュールに接続する場合には、付属の2.5 mmオス型フォノプラグをお使いいただけます。モジュールには、電源接続用に2.5 mmメス型フォノソケット付きの長さ457 mmまたは610 mmのケーブルが付いています。
取付けオプション
Ø8 mmならびにØ11 mmの筐体は、右や上の写真のような取付け用アダプタを使用することにより当社のオプトメカニクス部品のラインナップに取り付けることができます。アダプタを使用することによって、レーザーモジュールはSM1内ネジ付きマウントやØ25.4 mm(Ø1インチ)穴付きマウントに直接取り付けることが可能です。各アダプタの詳細と当社のオプトメカニクス部品との適合性については下記をご覧ください。
当社では、Ø11 mmのレーザーモジュール用にミニシリーズのキネマティックマウントもご用意しています。このマウントは当社の製品の中ではもっとも小型のキネマティックマウントで、Ø6 mmミニシリーズポストに取り付けられるようにM3タップ穴が付いています。
また、キネマティックマウントKM100T、ポスト、ポストホルダ、べース、そして5 VDC電源をすべてセットにしたモジュール取付けキットをご用意しております。レーザーモジュールCPS635F、CPS650F、CPS670Fに付いている焦点調整用の刻み付きノブは、取付けアダプタの内孔よりも大きくなっていますのでご注意ください。焦点調整型モジュールをコリメート型と同様の方法で取り付けるために、ノブを一旦取り外すことができます。取り外す前にノブを固定している止めネジ(セットスクリュ)を緩めてください。緩めずに作業するとネジを破損させる恐れがあります。また、初めにコードとフォノプラグをアダプタに通してからモジュールに取り付けてください。

レーザの安全性と分類
レーザを取り扱う際には、安全な操作の実施と、安全に関わる器具や装置を適切に取扱い、使用することが重要です。 ヒトの目は損傷しやすく、レーザ光のパワーレベルが非常に低い場合でも起こります。 当社では豊富な種類の安全に関わるアクセサリをご提供しており、そのような事故や負傷のリスクの低減にお使いいただけます。 可視域から近赤外域のスペクトルでのレーザ発光ではヒトの網膜に損傷与えうるリスクは極めて高くなります。これはその帯域の光が目の角膜やレンズを透過し、レンズがレーザーエネルギを、網膜上に集束してしまうことがあるためです。

安全な作業および安全に関わるアクセサリ
- 当社では、わずかでも影響のあるレベルのレーザ光線(例：クラス 1よりも高いクラスのレーザ機器)を取り扱う場合は、ネジ回しなどの金属製の器具が偶然に光の方向を変えて再び目に入ってしまうこともあるので、レーザ保護眼鏡を必ずご使用いただくようにお勧めしております。
- 特定の波長に対応するように設計されたレーザ保護眼鏡は、装着者を想定外のレーザ反射から保護するために、レーザ使用装置の近くのわかりやすい場所に置いてください。
- レーザ保護眼鏡には、保護機能が有効な波長範囲およびその帯域での最小光学濃度が刻印されています。
- レーザ保護カーテンやレーザ安全保護用布は実験室内での高エネルギーレーザの遮光にご使用いただけます。
- 遮光用材料は、直接光と反射光の両方を実験装置の領域に封じ込めて外に逃しません。
- また当社の筺体システムは、その内部に光学セットアップを収納し、レーザ光を封じ込めて危険性を最小限に抑えます。
- ピグテール付き半導体レーザは、他のファイバに接続、もしくは他のファイバから取り外す際には、レーザ出力をOFFにしてください。パワーレベルが10 mW以上の場合には特にご注意ください。
- いかなるビーム光も、テーブルの範囲で終端させる必要があります。また、レーザ使用中には、研究室の扉は必ず閉じていなければなりません。
- レーザ光の高さは、目線の高さに設定しないでください。
- 全てのレーザビームが水平を保って直進するように、実験は光学テーブル上で行ってください。
- ビーム光路の近くで作業する人は、光を反射する不要な装飾品やアクセサリ(指輪、時計など)をはずしてください。
- レンズや他の光学装置が、入射光の一部を、前面や背面で反射する場合がありますのでご注意ください。
- あらゆる作業において、レーザは必要最小限のパワーで動作するようにご留意ください。
- アライメント作業は、可能な限りレーザの出力パワーを低減して行ってください。
- ビームパワーを抑えるためにビームシャッタやフィルタをお使いください。
- レーザのセットアップの近くや実験室には、適切なレーザ標識やラベルを掲示してください。
- クラス3Rやクラス4のレーザ(安全確保用のインターロックが必要となるレーザーレベルの場合)で作業する場合は、適切な警告灯などをご用意ください。
- 適切なビームトラップを用い、代用品としてレーザービュワーカードを使用したりしないでください。
レーザ製品のクラス分け
レーザ製品は、目などの損傷を引き起こす可能性に基づいてクラス分けされています。 国際電気標準会議(The International Electrotechnical Commission 「IEC」)は、電気、電子工学技術関連分野の国際規格の策定及び普及を行う国際機関で、 IEC60825-1はレーザ製品の安全性を規定するIEC規格です(対応するJIS規格はJIS C 6802)。レーザ製品のクラス分けは下記の通りです:
| Class | Description | Warning Label |
|---|---|---|
| 1 | ビーム内観察用の光学機器の使用を含む、通常の条件下での使用において、安全とみなされているクラスです。 このクラスのレーザ製品は、通常の使用範囲内では、人体被害を及ぼすエネルギーレベルのレーザ光を放射することがないので、最大許容露光量(MPE)を超えることはありません。 このクラス1のレーザ機器には、レーザをシャットダウンするか、筐体等を開かない限り、作業者がレーザに露光することがないような、完全に囲われた高出力レーザも含まれます。 |  |
| 1M | クラス1Mのレーザは、安全であるが、望遠鏡や顕微鏡と併用した場合は危険な製品です。この分類に入る製品からのレーザ光は、直径の大きな光や拡散光を放射し、ビーム径を小さくするために光を集光する光学素子やイメージング用の光学素子を使わない限り、通常はMPEを超えることはありません。 しかし、光を再び集光した場合は危険性が増大する可能性があるので、このクラスの製品であっても、別の分類に移動する場合があります。 |  |
| 2 | クラス2のレーザ製品は、その出力が最大1 mWの可視域での連続放射光に限定されます。瞬目反射によって露光が0.25秒までに制限されるので、安全と判断されるクラスです。 このクラスの光は、可視域(400～700 nm)に限定されます。 | |
| 2M | このクラスのレーザ製品のビーム光は、瞬目反射があるので、光学機器を通して見ない限り安全であると分類されています。 このクラスは、レーザ光の半径が大きい場合や拡散光にも適用されます。 |  |
| 3R | ビーム内観察を行わなければ、このクラスのレーザ製品は安全とみなされます。 このクラスでは、MPE値を超える場合がありますが、被害のリスクレベルは低いクラスです。 可視域の連続波のレーザの出力パワーは、このレベルでは5 mWまでとされています。 | |
| 3B | クラス3Bのレーザは、直接ビームを見た場合に危険なクラスです。 ただし、拡散反射は有害ではありません。 このクラスで装置を安全に操作するには、ビームを直接見る可能性のあるときはレーザ保護眼鏡を装着する必要があります。さらに、インターロック機能付きの自動表示灯等の警報装置を設け、それらがONにならない限り、レーザがONにならないようにすることが求められます。 クラス3Bのレーザ機器には、キースイッチと安全保護装置が必要です。 |  |
| 4 | このクラスのレーザは、皮膚と目の両方に損傷を与える場合があり、これは拡散反射光でも起こりうるとみなされています。 このような被害は、ビームが間接的に当たった場合や非鏡面反射でも起こることがあり、艶消し面での反射でも発生することがあります。 このレベルのレーザ機器は細心の注意を持って扱われる必要があります。 さらに、可燃性の材質を発火させることもあるので、火災のリスクもあるレーザであるとみなされています。 クラス4のレーザには、キースイッチと安全保護装置が必要です。 |  |
| 全てのクラス2以上のレーザ機器には、上記が規定する標識以外に、この三角の警告標識が表示されていなければいけません。 |  | |

(posted 2019-09-24 12:31:26.567) Are there any problems known for the CPS635R suddenly losing its intensity? I got a set-up running with the CPS635R and after two weeks it lost its power completely. Also, it looks like some kind of obstruction is in its path (like a hair in front of the lens).
Any suggestions on what this can be? I think I have to order a new one... MKiess

(posted 2019-04-26 00:08:19.44) Hi,
We have a CPS532 laser diode module that we are incorporating into our microscope. We have the LDS5 power supply and that works great, but we are integrating all the electronics and power for them into one area and would like to use a different power supply.
I was wondering if you give me more information about the power requirements for the CPS532. Does the power supply for the laser diode need to be current controlled or just voltage regulated? Does the laser diode have internal circuitry that regulates to voltage or current? How much power regulation is required to maintain a constant steady output? Etc. wskopalik
(posted 2019-04-30 04:17:30.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry!
The CPS532 needs a DC operating voltage of 5V which can e.g. be supplied by the LDS5/LDS5-EC or by the CPS1 battery pack. Other DC voltage sources with a flat 5V output voltage would of course work as well. The flatter and more constant the supplied voltage is, the more stable the laser will work.
The CPS laser diode modules are internally operated in constant-power mode, i.e. you have a feedback from an internal photodiode which is used to maintain the optical output power. These diodes are however not thermally stabilized, so their optical output power may fluctuate slightly during operation.
I will contact you directly to provide further assistance. ggorju
(posted 2018-11-07 09:10:03.977) We would like yo know the spatial coherence length of the CPS module. There is several posts asking this question but never an answer nreusch
(posted 2018-11-15 07:20:09.0) This is a response from Nicola at Thorlabs. Thank you for your inquiry. I am very sorry about the fact that we cannot specify coherence features for the CPS modules. Unfortunately, we do not have data about the spatial coherence length or area for these modules. The temporal coherence length, however, is related to the spectral emission bandwidth. A typical spectrum for each module is shown in the spec sheet. Please note that these plots are typical only and will vary from unit to unit. In some cases, the resolution of the spectrometer/OSA is not sufficient to show the actual linewidth. Furthermore, the temperature of the CPS modules is not actively controlled and for some modules, you will see that temperature also affects mode distribution. michael

(posted 2018-09-21 02:13:28.0) This is a response from Nicola at Thorlabs. Thank you for your inquiry. A list of suitable light sources for our red-sensitive as well as our green-sensitive holography plates is shown at https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_ID=6716&tabname=Other%20Components. We also recommend diverging the light of a collimated source by means of a lens. If you would like us to recommend a diode for your specific application, please do not hesitate to contact us with further information about your setup. karol.686

(posted 2018-07-10 17:34:33.127) Hi! We are using several different CPS modules in a custom built mount that happens to electrically connect the aluminum housings. We learned that typically the housings are electrically isolated from +/- leads. However, sometimes it's not the case, to a point when a module would turn on undesirably by receiving power from am adjacent module via the connected housings. I could not find any info on the housing wiring/isolation vs +/- leads. If the parameter is not rated, is it in principle model-specific of sample-dependent? Thanks! swick
(posted 2018-08-09 03:56:32.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry.
The CPS modules are not isolated. We recommend to use floating supplies or the modules need to be mounted in an isolated way.
I contacted you directly for assistance. paul.janin
(posted 2018-05-09 17:09:06.67) Hello, I'm interested in the CPS 635R. Are there any internal electronics that would limit the input voltage bandwith? Would this diode be suitable for modulation in the 100 kHz - 1MHz range? YLohia
(posted 2018-05-09 01:45:41.0) Hello, thank you for contacting Thorlabs. The CPS line of diodes can only be used in a constant power mode, which prevents any modulation capability. biegel
(posted 2018-01-15 14:16:06.253) I have a cps532 laser. I am driving it with an LDS5. The output light intensity wanders over 50% with occasional jumps in power and occasional high frequency noise. The description mentions internal photodiode feedback control. How does that work internally? Perhaps that is defective? YLohia
(posted 2018-03-02 09:41:49.0) Hello, thank you for leaving feedback regarding CPS532 and my apologies for the problems you are encountering with your unit.
The photodiode is not built-in, since this is a frequency-doubled module and the pump diode is 1064nm (there is a filter to attenuate this wavelength before it hits the photodiode). It is quite likely that this problem is caused due to a thermal issue as the diode and crystal continue to warm the output power cycles, or perhaps the temperature of one of the components is cycling. These 532nm units tend to be particularly sensitive to temperature due to the non-linear crystal inside. Providing some heatsinking could fix the issue. Sometimes issues like this can also be caused by power supplies that are not outputting a constant 5V.
I have reached out to you directly via email to troubleshoot this further. wolter
(posted 2017-12-30 14:01:48.137) Hello, I am interested in the CP980S. Could you state an approximate value for the beam quality factor or alternatively the typical beam divergence (the data sheet states a max. divergence of 1.5 mrad) and the position of the waist? nbayconich
(posted 2018-01-15 05:09:40.0) Thank you for contacting Thorlabs. At the moment we have not measured the M^2 quality factor for these CPS laser diodes. The M^2 factor will be similar to our other fabry perot laser diodes. For improved beam quality, a spatial filter could be used, but that would reduce the total power. christopher.little
(posted 2017-12-15 10:00:41.973) Are the beams of these products p-polarised or s-polarised (vertical or horizontal)? tfrisch
(posted 2017-12-15 08:34:01.0) Hello, thank you for contacting Thorlabs. The internal laser diodes are typically TE polarized. However, as the housing of the tube is cylindrical, you may rotate the entire unit such that the polarization is either vertical, horizontal, or any arbitrary linear state. apespejo

(posted 2017-09-26 02:21:08.0) Hello, thank you for contacting Thorlabs. Coherence length will be related to the bandwidth of the laser which can change with temperature. I would estimate the coherence length at roughly 70 to 700um. I will reach out to you directly to discuss this. Simone.I.Rupp

(posted 2015-09-10 07:56:32.193) I noticed that the collimated beam profiles of your laser modules are very nice and homogeneous.
Do you sell the collimation lenses in these modules as separate products or would you be able to sell them to us independently of the laser modules ?
The reason I'm asking this is because I have difficulties getting homogenous collimated beams using the standard Thorlabs molded aspheres because they produce lots of ring-like features in the collimated beam. I also have a CNC polished asphere from Thorlabs here which seems to show the same ring-like intensity modulation.
My light source is a superluminescent diode at 840nm with beam divergence angles of 10 and 30 degrees. besembeson

(posted 2013-05-10 15:04:25.723) I've been using the CPS196 for alignment for various alignment tasks for several months. Yesterday, while moving it, one of the power leads broke off the exposed circuit board on the back. The shrink tube had slipped off. I was able to solder the lead back on and it works again, but I'd just like to add my $0.02 and say I'd appreciate a unit with a more robust power connector. Cheers! tcohen

(posted 2012-06-29 09:19:00.0) Response from Tim at Thorlabs: You are correct that the photodiode is not directly connected to the outside world. The CPS modules have two wires for the power supply. This feeds an internal integrated driver, which is what actually controls the power using the internal photodiode for feedback. user

Because from the web photo of cps196, I only found two wires at the back end of the laser, which must be power supply, so the internal photodiode is not connected to the outside world, how can there be a feedback? I am puzzled, please help here.

(posted 2011-06-14 16:27:00.0) Response from Javier at Thorlabs to dfwenge: Thank you very much for contacting us with your inquiry. Regarding question (1), we actually had not considered adding a strain relief assembly to these laser diode modules before. I will discuss your suggestion with our electronics design engineers and get back to you. Also, you can certainly solder the the leads back onto the circuit board; I would not expect any damage to the laser diode from doing this. (2) We do offer pinholes; however, the maximum size that we stock is 150 um. Nonetheless, we can offer a 250 um diameter pinhole that you could adapt to the front of the CPS182 as a non-standard item. I will contact you directly for further discussion.

(posted 2011-06-06 11:28:14.0) I have 2 comments:
1. After using a CPS182 laser module in a experiment where the laser is often moved to various postions the power leads have broken off the connectors. I have strained relieved the power cables on a spare unit using shrink tube. This seems to work okay but it takes up more space than I would like. Have you considered providing a strain relief design on the units you sell? If I try to solder the leads back on the connector, is there a potential to damage the laser diode by overheating?
2. Do you sell a pinhole, say around 250 microns in diameter, that would mount on the front output plate of the CPS182.

(posted 2009-04-15 15:36:55.0) Additional Response from Laurie at Thorlabs to Aidi: Upon speaking to a colleague here, I would like to add to my previous post. The main issue you will have is noise. Due to mode hopping as the diode temperature changes or as the diode ages, there will be times that the laser is hopping between two longitudinal cavity modes. Additional noise sources could come from the servo loop. These products are designed as alignment tools and not as low noise optical sources. For low noise performance, a constant current drive with a temperature-controlled mount is recommended. The user then needs to find a stable operating point in both current and temperature. Also the user should know that this stable operating point may change with time. We hope this additional information is helpful. Laurie
(posted 2009-04-15 14:58:34.0) Response from Laurie at Thorlabs to aidi: We do not have concise data for the power stability of our CPS modules compared to one with a TEC controller. The laser diodes in our CPS laser modules are operated in constant power mode, which makes them very stable in terms of optical power. However, since there is no temperature control for these diodes, heat can build up in the junction causing instability. Although this instability will be small for low powers, a TEC-controlled environment will definitely lead to more stability. aidi
(posted 2009-04-15 05:09:54.0) How good its optical power stability compared to the one used TEC controller? Thank you Laurie
(posted 2008-10-09 08:50:57.0) Response from Laurie at Thorlabs to g.gray: Thank you for your comments and feedback. We greatly appreciate hearing from our customers concerning possible extensions to our product lines. Currently, we are in the process of expanding our laser diode module offerings, but none of the items in the pipeline are for the wavelengths you suggest. Thorlabs has an internal forum where product ideas can be posted. I will be sure to add your suggestion to that list in the hopes that it will be adopted. As an alternative, you might consider our unmounted laser diodes, which are offered at both of these wavelengths and can be found on our website at this link: http://www.thorlabs.com/NewGroupPage11.cfm?ObjectGroup_ID=7
Thorlabs also offers aspheric lenses for collimation and laser diode mounts if you decide to pursue this avenue. g.gray
