Well, that is right interesting. Two rows of diodes is easier to deal with than four. Of course, the question still remains – what are we gonna do with it. We'll burn that bridge when I get to it, I guess. By the way, while we cant use matrix lasers individually, I don't know that it will always...

Searching for a clue, I wanted to see the beam shape of an uncollimated laser. A blue 7 Watt NUBM44 was on hand. A piece of white paper was put in the beam path about an inch from the front of the 12mm diode mount. The beam was less unattractive than I had expected, but the ends are truncated...

Yes, and you're lucky, 'round here, we don't get night air – not even at night.

Good plan From Encap's reply, I decided to look up the SLD light. The technology looks good, when it's available. It should be no problem making, or buying a driver for these without great expense.

ACCEPTABLE

If starting from 12V... I might be inclined to do something quick and dirty, like a 5 volt regulator or just resistors. One gets no extra credit for making something efficient. Throw in a capacitor and resistor to deal with transients. Good enough is the enemy of better. Laser tail lights...

Maybe not, then :confused:

I dunno, what did it look like before? 😁

I say NO to the specifically protected driver requirement, it is not so. I too, have never seen a higher voltage laser diode specific driver. Actually, I have never used a laser diode driver. There are options which are less idiot-proof but are much more flexible. A plain bench power supply...

That makes sense to me as well. I am inclined to use modules rated for well above the current required. Some suppliers exaggerate their capacity. OK!! I have to take the gang lens off, in any case. I don't know if I have a suitable dark glass bottle, but should be able to find something. I have...

Sigh, I always have trouble. ;) Yes I≠A, R≠Ω, E≠V I knew this stuff 60 years ago, but don't use it often enough and my braincell had a parity error. Back then, we had to use "O" and "I" because and had not been invented, yet. Agreed, although there are fuses that are extra fast, it...
