]]> 0 NUBM44 laser suddenly stopped working – driver or diode failure? Fri, 19 Dec 2025 00:33:23 +0000 https://laserpointerforums.com/threads/nubm44-laser-suddenly-stopped-working-%E2%80%93-driver-or-diode-failure.112047/ 112047 invalid@example.com (Roger Andrade) Roger Andrade Hello everyone,

Some time ago I built a laser with the following setup:

Diode: NUBM44 (7W)
Driver: SXD 4.5A
Host: Survival Laser
Power: 2× 18650 Li-ion batteries

The laser worked fine for a while, but recently it suddenly stopped working. A friend helped me with the build and did all the soldering, since I don’t have much experience with electronics myself.

Is it possible that either the driver or the diode has failed?
Is there any safe way to test the diode directly...

So my safety tail connector of my laserpointer broke. I'm talking about this thing:

The model is:

PL-532F-300B

It's basically a 532nm 300mw laserpointer that I bought from laserbtb in 2016.
Can anyone tell me where I can find this thing in the pic? Without it, my laser is unusable...

Does anyone know the schematic of a driver board ~16mm x 10mm with a LM358 I.C, a tact switch and a couple of transistors and few resistors supposed to drive a 1500mW violet, was inside a 14mm pointer tube ? No potentiometer trimmer.

Osram now has NUBB, NUBE array format formerly known as QuaLas by Nichia but Osram calls them VegaLas.
I've attached the datasheet of both below.

The new VegaLas PLPM7 455QA_LL (42W @ 455nm typ)

Is the clone of

The old QuaLas NUBB24 (44W @ 455nm typ)

I'm having a problem with both the internal and external threads on hollow aluminum tubes. I can't figure out which measurements to use for the internal ones and Which for the external ones, especially on the part that acts as a cap. For example :
If I have an aluminum tube that measures 4 cm from end to end, once the external thread is threaded, how do I screw on the other part,
The internal threaded cap?
That's all.

In the future I will buy another one that can have a longer focus.. Everything will be in a box again. There will be cooling with a powerful fan and the array will be...

I'm confused: why is there a red dot when it's turned on? Aren't infrared lasers supposedly invisible to the naked eye?

I tested it, and it quickly set cardboard boxes on fire. I pointed it at a cockroach in my house, and it quickly cooked. Very interesting; this shouldn't be considered animal cruelty, right?

But from what I could tell, the BDR-209 is technically the Blu-ray Disc drive marketed by Pioneer Corporation. I could barely find any official specs about the diode itself.

The fact that 405 nm lasers can go well over 1 W suggests that the nominal output of the BDR-209 diode is very high. However, most of the single-mode 405 nm diodes I could find are of low power, like...

The color? Purple! Not the strange 405nm violet or the purplebluish from 445nm blue, it’s purple for me!

I have no ideia of how much power this is doing as I don’t have a LPM.]]> 9
