Just took apart and photographed the Atomstack module I got. It's posted in this thread: https://laserpointerforums.com/threads/20-watt-atomstack-m100-laser-module-tear-down.109530/

I bought this new 20-Watt laser engraving module for R&D. I took it apart and photographed it each step of the way. I put it back together after and I'll probably put it on my CNC machine at some point.

I would think knife edging would be the way to go but their pictures make it look like the beams are going through dichro mirrors but I don't really think that's possible. I also imagine they're using the NUBM05/06/08 diodes. There's a chance they're using the re-canned FAC diodes but who...

I ordered the Atomstack version. It should be delivered tomorrow if USPS gets their $hit together. I'm very curious exactly how they're combing the 4 diodes. https://shop.atomstack.com/product/pre-order-atomstack-m100-130w-quad-laser-module-with-air-assist-system/

Doesn't look like there's a price break unless you buy 100+ pointers.

I will certainly check this out when I have a moment.

You must use a current regulator. Never connect laser diodes directly to an unregulated power source. Your datasheet says ≤450mA. You'll likely want a buck driver.

Yes, the ebay links are in the post right before yours.

If the diode window isn't actually cracked or pitted then you can clean it. Try some compressed air first. If that doesn't work then I typically use brake cleaner and compressed air. It's a powerful solvent that doesn't leave any residue behind and it's a non abrasive way to clean the window...

Link works for me too.

Wecome back! You can check out what I have available in my ebay store and website. I also build custom lasers from time to time.

Anyone know where to buy transparent phosphor lenses?

Looks like a standard TO-5 diode pressed into some sort of lens and possibly phosphor type fixture...
