I would like to experiment with this NUBM0C, comparing it with a NUBM44-V2, their applications on graving/cutting purposes can reduce the cost of CNC machines (US$72 vs US$150).

Thanks so much guys! I was bad at my reasoning about laser length, so the higher the wave length of the beam, the better the absorption of materials, right? I've already made some tests, and with a NUBM31T at maximum of consumption, burning some stuff is greater than a 100W CO2 laser tube, it...

Hey guys, I have two questions related to optical power. 1- If you have an optical output of 5W from a laser diode, 5W from a CO2 laser, and 5W from a fiber laser, is the output power the same? Do the origin nature of the laser beam (semiconductor, gas, etc) has an effect in the final beam...

Can you send us images of your project? So we can have a better idea.

If you add a series resistor (for example 1k) with the batteries, you should be able to see the dot, maybe there's lacking of voltage (secondary drive) to run the current (main drive). I had the same situation with some experiments using a NUBM31T. You must check your datasheet and see the...

It could be reverse polarized, most of the diodes has a reverse zener diode protection, in most of the cases Red =+VCC & Black = GND.

Lovely laser color, I was wondering what's their maximun output power? Does it has a reverse zener diode protection? What's the time life? BTW AWESOME graphics, what software did you used?

There's a laser module sensor from IFM, the O1D300 that uses an 650nm laser, <5mW for sensing applications with a range of 9 meters, it has a spam of 0.20 meters, so the final effective area is 8.8 meters, you can use this reference as your starting point.

Men looks awesome! Does the laser that you used has a model? I would like to do the same but with some chemical additions.

Well, if you say so it must be true, yeah, i think you're right and I'll improve, so... thanks for the advice? I'm going to implement all your feedback into my next project, I'm sure that I could be a great support for my next projects? well, hope the best for you kid. Forgot to mention to be...

'Cause pandemic is limiting german market you should take in consideration other options. Why don't you make your own laser driver? you can use this example if you want: https://electricaldarkness.wordpress.com/2021/05/31/control-and-power-circuit-for-nichia-nubm44-v2/

It's curious how companies are trying to steal our right to repair our electromechanic equipments, with Philips's programmed obsolescence the long term products were dying in order to produce more sells in the name of i+D+I. This week on deutsche welle congresists pronounce for a more stricted...

Emilia is love, Emilia is live. Awesome pictures! an RGB crystal could a perfect addition to your next session.

I used AWG#22 full copper to control that specific diode, you can supply an average of 4.5A, but in my personal experience for a V2 you can run it at 5A maximun, but laser's longevity is reduced.

Your circuit looks cool! my corcern is related to the warm, 'cause the PL540B losses power efficiency due this factor, an small heat sink and a FAN o the PCB can improve this problem; you need a reverse protection circuit for the PL540B, most of them doesn't have a reverse zener diode...
