Hey guys, I really need to know who makes this laser diode. L638P200 Thorlabs doesn't provide any documentation and also it's very expensive on Thorlabs. Thanks a lot.

That's what I have done so far. The 450 nm lasers I have all show lower than 450 nm. For my color illumination, I need higher blues. I like closer to 465 nm even better. It needs to be single-mode since I'm illuminating a diffraction grating. I have a few TopGan 460 lasers, but super expensive...

Hey guys, Anyone selling low-power (under 200 mW) single-mode 460 nm blue laser diodes? I need 10-20 of these! Thanks,

Thanks, I bought one from the Dragon Laser website. Measuring reflection and transmission on a specific material is my application.

Hello all, I'm looking for a 589 nm laser under $1000. Are you aware of any websites selling those? I don't need long coherence length and 1-5 mw is enough for my application. I need to be able to collimate it to a 1 cm beam. Thanks,

The Opt Laser one is super expensive. I am looking for a unit closer to $50-100. I found this one, I'll try it and let you know about the quality. RGB-300mW-White-Laser-Dot-Module-Red-Green-Blue-638nm-520nm-450nm-TTL-Driver-Modulation-p-1252293 Google that one. I can't post a link until I get...

Is it possible for you to send me some links? I'd appreciate that.

The problem with that is the RGB units out there are not very well aligned. But do you have any specific small RGB units in mind? Brands? Company name?

Hi All, I'm looking for a compact RGB collimated unit which outputs a 1-inch, aligned, collimated beam. I haven't been able to find an appropriate one. Do you guys have any suggestions? If you know a supplier or specific company, please send me the link.

Yeah, I just found one on eBay. Hopefully, they're what I need. Circular RGB output shape.

Laser Size is very important to me. I want them as small as possible just like the green OPSL one. I'm using laser diodes now but they suffer from astigmatism and ellipticity. I can correct the output with more optics but that will make everything bulkier. So basically I want cheap small...

It's the heater. I added a POT for the heater, somewhere in the middle it works really nice. At the wrong temp. you might excite differentlaser modes like TE20, Isaw it myself.

Hey, thanks for introducing this laser. The output is super nice. Here's a picture of the laser running. I printed the driver (conductive ink) in-house and ran it without a fan with a 9 v power supply. The LM317s get super hot even with two heatsinks on them. I had to add a fan to cool it down...
