Not sure where to put this but I'm looking to take on a large knife-edging and beam combing project. As you may guess, it's for a huge laser gun. :p My 200W laser bazooka had terrible beam specs, but with proper mounts and optics I can do a lot better. Esco optics is willing to make me some custom coated optics for the project, but I will need a lot of mounts.

So what are the cheapest mounts for diodes/mirrors out there? I'd prefer direct diode mounts as those will have less error than sticking a 12mm module in with a set screw.

I like these 4x diode mounts from lasertack but they aren't cheap. Plus I need more room for corrective optics than what they give in their knife edging setup.

These look cheap but individual diode holders means additional alignment. One pro is that the mounts can be staggered to keep beam path distances equivalent.

As for mirror mounts, lasertack looks to be the cheapest out there:

Anybody know of cheaper sources out there? Particularly for bulk orders?


I'm looking to combine 445nm and 465nm knife edge arrays with a dichro, and possibly add some PBS cubes in the mix for higher power (I see PBS cubes becoming very lossy w/ multimode diodes though). Still have lots of decisions to make on beam correcting.

i've been looking at a few holders with cheap lenses on ebay;

https://www.ebay.com/itm/Rose-coppe...m-Laser-Diode-w-red-optical-lens/332255830331

https://www.ebay.com/itm/Red-Copper...aser-Diode-with-450nm-glass-lens/142506895324

https://www.ebay.com/itm/Brass-Lase...m-Laser-Diode-w-450nm-glass-lens/141410341265

These don't have lenses, but are cheaper, maybe all of these are low quality, I don't know;

https://www.ebay.com/itm/To18-Laser...uitable-for-5-6-mm-M9x0-5mm-1pcs/232153708440

edit; the quality might be better on this, it has close up photo's allowing you to see better;

https://www.ebay.com/itm/Brass-Laser-Diode-mounts-9mm-for-M9x0-5-lens/322686742166

Not cheap, but a lot of nice things; https://www.ebay.com/sch/optlasers-com/m.html?_nkw=&_armrs=1&_ipg=&_from=

DTR says out of stock, but I bet if you ask, he might have one or more; https://sites.google.com/site/dtrlpf/home/knife-edge-arrays

Thanks for the links. Looks like these 9mm mounts from ebay are cheapest. I probably won't need those lenses, but the copper versions look nice.

I'm still trying to evaluate whether I can deal with the ball lenses in place or if I'll have to decan and use my own.

BTW I have a huge box of those knife edgers from DTR. :D They are alright for combining the diode blocks from the projectors they were designed for, but I imagine they would be awful for a setup from scratch.


I have some of those rose copper 9mm diode blocks and they fit well, the hole for the pins is centered but that's no different than our 12mm round modules when you use a solid copper back.

Thanks for the link! I like the idea of going copper for these high powered laser diodes.

I assume you've checked out Edmund Optics?
