I was just messing with you. It's attached to a large copper plate with heat pipes going to a finned heatsink.

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.

It's basically the same way they're cooled in the projectors they come from.

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.

I decided to build a laser blaster using the NUBM34 laser diode array. This thing is insane! I ran two rows of diodes in parallel to the other two. Powered by a Milwaukee 18V battery pack and this is the boost driver I used
Hello from Switzerland
how many volts and how many amps are ideal for this configuration?
i will get the same laser diode soon!

thanks

depends how you wire them.... if they're all in series then it's upwards of 100 volts
