QuaLas arrays (numb12 modules)

Time to horde diodes

Single emitters will get stronger and will be more cost effective, in the future.
I expect we will see projectors with 1R, 1G, 1B and maybe a yellow laser diode and as quantum dot diodes will be less expensive to produce as well as more efficient, we should see an end to these cluster arrays in favor of stronger and higher quality single emitters..... that said wrecking a new projector to get a diode that you can't otherwise buy yet will be more expensive when there are only 1 of each inside.

Laser Diode Market Size, Share, Industry, Trends and Growth Analysis 2032

The global Laser Diode Market Size in terms of revenue was estimated to be worth $5.9 billion in 2022 and is poised to reach $10.9 billion by 2027, growing at a CAGR of 13.1% during the forecast period.

Well I’m assembling a full set op opsl 2w modules with Saturn scanners rygb. This will be my last ever projector. If that’s not good enough it never will be. Just need to get a yellow. I see one on eBay for 8k….nope.

Agreed, kecked! Hopefully affordable laser pointers and engravers aren't on their way out!

Looks like not as good optics on that case I do believe these are first generation reds from Nichia so that could be it too i mean 2.5W per LD I'd expect them to be dual beam but looks like single beams so thats in the correct path at least.

@Gryphon they are dual beam reds?

 

[Gryphon]

Yes, the reds are dual beam

A long time lurker on the forums and finally posting. I have been reading a lot over the last few months and already learnt a lot here.

I recently bought a few NUBB14s and a NUMB12 and have been testing them. Crazy how small these things are and the amount they punch into such a small package.

I've recently tried to solder some wires for a bit more permanent setup but it keeps melting due to the heat generated from running the lasers. I know this is partly a cooling issue - and while testing it's a simple setup - but I havent used thermal paste, etc yet. Eventually I'll likely use thermal glue and a permanent mount or heat sink.

Any suggestions on how others are connecting to these or should I really just be keeping the heat down?

If your diodes heat so much your solder melts you are either going to kill them dead in minutes or are using eutectic solder! You must heat sink these always. There is no coming back they are likely damaged.

Unlikely, unless we find some totally new materials to make them from. The AlInGaP and AlGaN can take only so much power density. If single emiter sources will have higher power they'll have even worse beam in slow axis

Thanks, used some thermal paste and makes a world of difference!

I think I killed one of the NUBB14s I got, it's still turning on now but only draws a max of 1.4a - which seems a lot lower than the 3a it's rated at. Lucky I got a few of them!

Once they get damaged it cascades and they fail. Might take a in but they fail. The blues are pretty robust but not perfect.
