激光安全和分类
使用激光器时应遵循安全规章并使用正确的安全设备。眼睛极易受激光伤害，即使是极低的光强。Thorlabs提供一系列安全配件，可用于减少事故风险或伤害。可见光和近红外激光最有可能造成视网膜损伤，因为这些波长能够透过角膜和晶状体，而且晶状体会将激光能量聚焦到视网膜上。
 |  |  |
 |  |  |
 |  |  |
安全实践和光安全配件
- 使用Class 3或4激光器时，必须佩戴激光防护眼镜。
- 工作中无论何时使用功率不可忽略的激光，Thorlabs建议佩带激光防护眼镜，因为螺丝刀等金属工具可能意外反射激光。
- 设计用于特定波长的激光安全眼镜应摆放在激光装置旁边明显的位置上，让佩戴者免受意外反射的激光照射。
- 安全眼镜上要标注可防护的波长范围以及那个范围内的最小光密度。
- 激光防护帘和激光防护布可以防止实验室其他区域受到高能激光。
- 遮光材料可以阻挡来自实验装置区域的直射和反射光束。
- Thorlabs罩壳系统可用于遮盖光学装置，以此隔离或减小激光危害。
- 带尾纤的激光器在连接或断开其它光纤时必须先关闭，尤其激光功率水平高于10 mW。
- 所有激光需要终止于平台边缘，激光使用时实验室要关门。
- 激光光高不能和视线平齐。
- 在光学平台上开展实验，使得所有光束沿水平方向传播。
- 靠近光路工作时摘掉不必要的反射物件，比如首饰(戒指和手表等等)。
- 注意透镜和其它光学器件的前后表面都可能反射一部分入射光。
- 将激光功率设置为能够满足应用的最小值。
- 如果可能，在光路对准过程中降低输出功率。
- 使用光快门和滤光片减小光束功率。
- 在激光装置旁边或者房间里贴上正确的警示符号或标签。
- 在操作Class 3R或4激光器(即要求使用安全连锁的激光器)时，使用灯箱式激光安全标识。
- 激光观测屏不能替代合适的光阱。
激光等级
根据眼睛伤害和其它危害程度，激光器分为不同的几个等级。国际电工委员会(IEC)是制订和发布国际电气、电子及相关技术标准的的全球组织。IEC 60825-1标准文件概括了激光产品的安全问题。每种等级的激光器描述如下：
| 等级 | 描述 | 警示标识 |
|---|---|---|
| 1 | 这个等级的激光器在任何正常使用的情况下都是安全的，包括在光路中使用光学仪器进行观测。这个等级的激光器发射的激光在正常工作中不会导致伤害，并且不可能超过最大允许的曝光量(MPE)。Class 1激光器也包括一些封闭式高功率激光器，不去打开或关上激光器就不可能暴露在激光中。 |  |
| 1M | 除了和望远镜和显微镜等光学组件一起使用时，Class 1M激光器就是安全的。这个等级的激光器发射大直径或发散光束，除非经过聚焦或成像光学元件缩束，一般不会超过MPE。但是，如果光束重新聚焦，伤害可能增加，等级相应改变。 |  |
| 2 | Class 2激光限于1 mW以下连续可见光，这类激光器是安全的，因为眨眼反射会使眼部曝光时间限制在0.25 s。这个类别只适用于可见光(400 – 700 nm)。 |  |
| 2M | 因为眨眼反射，这个等级的激光只要不通过光学仪器观察时就是安全的。这个激光等级也适用更大直径或发散激光光束。 |  |
| 3R | 这个等级的激光只要以有限制的光束观测操作就是安全的。使用这个等级的激光器不可能超出MPE，但是也有低风险伤害。对于这个等级，可见连续激光输出功率被限制在5 mW。 |  |
| 3B | Class 3B激光如果眼睛直接曝光会造成危害。但是，漫反射没有危害。这个等级的操作安全措施包括在可能直接观测激光光束时佩戴防护眼镜。此外，需要安全互锁的激光器应和激光安全标识灯箱一起使用，使得安全灯箱不亮时就不能使用激光器。Class 3B激光器必需配备钥匙开关和安全互锁。 |  |
| 4 | 这个等级的激光可能造成皮肤伤害，也可能造成眼睛伤害，甚至是观测漫反射光都可能。这些受伤风险也适用于光束的间接或非镜面反射，甚至明显哑光表面也可能造成伤害。它们也有火灾风险，因为可能点燃易燃材料。Class 4激光器必须配备钥匙开关和安全互锁。 |  |
| 除了上面相应的标志，所有的2级(或更高)激光器必须显示这个三角警示标识。 |  | |

(posted 2024-01-23 11:27:40.983) Which is the maximum output power of the model S1FC405? ksosnowski
(posted 2024-01-23 11:50:22.0) Hello, thanks for reaching out to Thorlabs. Each unit is calibrated to achieve the maximum power for the particular laser diode used in the device. Due to variations in the coupling process, no two units will have the same exact maximum power. For S1FC405, we guarantee at least 8.0 mW on each unit we build. Ensuring that the patch cables used are always cleaned is an important measure to maintaining the output over the life of the laser, as any debris can cause backreflections which may damage the laser inside and cause reduced power. I have reached out directly to discuss this in further detail. Nazim Bharmal
(posted 2023-07-14 08:04:48.137) In your manual, there is no information regarding the modulation input connector type. That is only on the webpage (in small font) and via the 'Pin Diagrams' tab (arguably hidden). So I'd suggest modifying the manual to include the specification. cdolbashian
(posted 2023-07-21 11:50:13.0) Thank you for reaching out to us with this feedback. Within the manual, under the "Modulating the Laser Output" section (5.5), the first bullet point describes the required electrical connection. Regarding the hidden pin diagrams tab, we include such a tab on all pages which have devices with electrical outputs so that the information is visible and easily accessible without having to find it within a manual (in which it is also included). I have reached out to you directly to clarify this further. Tatsuo Yamaguchi
(posted 2023-07-05 13:26:23.857) お世話になっております。
御社のファイバレーザー光源S1FC660を購入したものです。
こちらの光源の光量のツマミを回したときの光量の安定するまでの時間についての仕様などはございますでしょうか？
感覚的な記述で恐縮なのですが、1mW→3mWまで光量を上げると、一度4mW程度まで上がりそのあと3mWまで下がるのに10-20秒程度かかっているという印象です。
よろしくお願いいたします。 cdolbashian
(posted 2023-07-14 04:11:48.0) Thank you for reaching out to us with this inquiry. A tech support agent has contacted your from our local office. user
(posted 2021-04-23 01:45:27.227) In my optical system,maybe about 20% laser power will back reflection into laser source.I am worried about back reflection light will damage laser source.Does this laser source include isolator?Thank you. YLohia
(posted 2021-04-23 11:35:06.0) Thank you for contacting Thorlabs. Unfortunately, such a high back reflection will damage the source since this doesn't come with an integrated isolator. That being said, a custom fiber based isolator for 635 nm can be ordered using the form on this page (https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3260) and be used right on the output to reduce the amount of backreflections going into the laser cavity. user
(posted 2019-05-21 14:13:05.223) In the product description you state
"... All of our fiber-pigtailed lasers utilize an angled fiber ferrule at the internal laser/fiber launch point to minimize reflections back into the laser diode, thereby increasing the stability of the laser diode's output."
And yet the specifications call out an FC/PC and not an FC/APC. I am confused. Can you please clarify? YLohia
(posted 2019-05-21 03:00:34.0) Hello, thank you for your feedback and bringing this typo to our attention. The specs are correct -- the items on this page (as of 5/2019) are FC/PC and not FC/APC (APC connections can be quoted as custom items by emailing techsupport@thorlabs.com). I am working with our technical marketing team to get this resolved. Please accept our apologies for any confusion caused by this. Andrey Kuznetsov
(posted 2019-05-01 14:28:16.583) NOTICE to Customers: I compared 630HP and SM600 fibers when connected to these Fiber sources. These sources have an internal SM600 fiber from the diode to the front bulkhead connector. Thorlabs rightly says to use cables of the same type, however even though 630HP and SM600 share almost exactly the same parameters like NA, etc, based on my tests: 630HP insertion can cause output attenuation up to 95%, while SM600 fiber attenuation was only up to 20%. The issue I had was that when inserting a fiber into the bulkhead, with the key polarizer aligned, rotating and tightening the connector would result in an unpredictable attenuation of light output as measured with a photodiode. We're now switching to SM600 fibers to avoid severe attenuation losses due to fiber coupling issues. Thorlabs should explicitly state this on the Overview page in bold letters that customers must use SM600 fiber to avoid huge attenuation losses due to coupling. mmcclure
(posted 2019-05-02 10:52:01.0) Hello, thank you for your feedback. Yes, for our single mode fiber-coupled laser sources, we recommend using a single mode patch cable that is the same fiber type as the fiber-pigtailed laser inside the device. We will make this recommendation more explicit on the webpage. akuznetsov
(posted 2018-09-27 19:42:45.16) What is the fiber core size inside these laser bench sources?
What core size fiber patch cable should I use to optimize light throughput? YLohia
(posted 2018-09-28 11:33:03.0) Hello, the fiber types used are listed in the Specs tab: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1500&tabname=Specs along with the MFD and NA. In order to maximize coupling efficiency, you should use the same fiber or a multimode fiber with a larger MFD and NA than the one used in the benchtop unit. akuznetsov
(posted 2018-09-27 17:33:36.43) We have a S1FC637 and we see that 637*2=1274nm wavelength is also present on the output, is this normal? Shouldn't there be a filter in the unit to prevent the doublet from outputting?
We are using the 637nm to excite emission in the NIR so the 1274nm output from the laser is interfering with out results. YLohia
(posted 2018-10-03 03:02:17.0) Hello, thank you for contacting Thorlabs. This is certainly not normal and not expected of a GaAs-based chip. I took a few scans of the S1FC637 with our OSA207C optical spectrum analyzer and did not find any significant emission around 1274nm (at max output power setting). Based on our correspondence, the issue was being caused by the small fraction of the stimulus light (1274nm) being fed into the spectrometer since the stimulus and collection path were the same. melanie
(posted 2018-09-04 08:20:38.627) 1.What is the laser threshold power for S1FC635PM ?
2.Would you consider making a PM fibre-coupled green laser ? nbayconich
(posted 2018-09-25 10:17:46.0) Thank you for contacting Thorlabs. We do not specify a threshold power for the S1FC635PM benchtop source however the setpoint resolution is 0.01mW and can be adjusted from 0 - 2.5mW. The threshold current for the diode is about 50mA and the minimum range is set to just below the lasing threshold. The output is mostly off but there will be a very small amount of light still present since a small amount of light is needed for the power control circuit to be active.
I will reach out to you directly to discuss our custom capabilities. melanie
(posted 2017-03-23 13:05:57.74) I have 2 questions:
1) If connected to one of your PM patchcords, what will be the typical polarisation extinction when the light emerges from the patchcord ?
2) If we turn the laser right down, will it become incoherent ? (this is useful to us)
Thanks,
Melanie tfrisch
(posted 2017-03-30 01:17:52.0) Hello Melanie, thank you for contacting Thorlabs. When used with a PM patch cable, S1FC635PM has an extinction ratio of >20dB. As for the laser power, this unit is not intended for operation below the threshold current of the diode. I will reach out to you directly to discuss your application. acable
(posted 2008-08-15 10:52:31.0) Related Products… please think about the related products that are most often used with the product that is being featured. In the case of the fiber coupled laser sources it would probably be: patch cable, collimation package, and perhaps a mirror mount and adapter to hold and aim the collimated light field.
I would even think about adding a little text by each price box with a labeled photo of the parts all connected together, with a kit being offered for each of the wavelengths. I would then use the Related Products links (and refer to them in the text) to allow the customer to put together their own parts list (longer cables, different collimation packages, different mounts). |
