I know. It is a really great build and I don't want to reinvent the wheel. Do you have more details about the build. I am surprised that passive convective radiation is sufficient to cool the diode array.
Hi guys, even if I read a lot here, it's been some years I did not post anything, but after I've found a new (for me at least) laser diode from Nichia (NUBM3HT), 137 Watts of pure pleasure, I had to speak out. So I wrote them a request for a quote and they replied by asking me about my company (incorporated) and what is my application for the diode. Of course, I want to give them the right answer in order to be able to get this ''beast''. I will consider your answers before I reply to them. Thank you in advance! Hope it will be available soon
Be expensive but really cool is that Chinese group that decans and puts corrective fiber on the diode could also remove them all and mount on a new plate with the emitters all next to each other. Then just water cool that. Would easily be less than 2” square. Then beam expand that. Says it’s for a laser cutter. Bet the beam could be Very tight. Especially if they crossed pairs with knife edging. Or one row hor and one vertical with a large pbs cube. Then knife the result. Might be cm square at aperture.
