The GH06C01A9G is a relatively new diode and nobody has posted using one yet, it would be interesting to see how high it can go when overdriven. However, it is rated at 1.2W and this thread is discussing options (or lack thereof) of red diodes that produce over 2W. It would be interesting to...
WATCH YOUR EYES and think before you apply power to that thing. Look where it’s pointing and predict any possible reflections it may bounce from. Don’t start fires unless you’re deliberately trying to. Use eye protection. If that’s your first laser or even if it isn’t jfc that’s a lot of...
I see capacitors on what appears to be the output side of the driver, be sure to short the output of the driver for a brief moment before connecting the array in case the capacitors are charged- otherwise they will dump as much current as they can provide for a brief blink of an eye and likely...
Heat sink the shit out of that driver. Who knows what its failure mode is and you don’t want a failed wide open driver, it will get hot hot hot. Also sorry I was writing my last comment while you had posted the specs for the driver while I was asking for that exact info.
Are you sure your clamp meter works with dc? DC clamp meters are comparatively rare as the vast majority of clamp ammeters are AC only. I’m confused how you don’t know what your driver will output necessitating your use of a an ammeter.. didn’t your driver specify what it’s output will be, or...
Lasertree sells a 2.1 watt, single emitter red diode with both linear and square FAC options available

I'd forget the NUBM07 and I'd suggest going with an NUBM0C instead. It's the same 465nm+ but rated at 4.1W instead of 2.9W of the 07 and has divergence between the 07 and 44. The divergence of the 0C is better than the 0G, 0F, 44, 08 etc. Use it with a G8 lens, run it at 4A and be happy with...
I believe it's single line as indicated by 2218-010SLCPEB and rated at 10mW, I remember most of the single line units seemed to be 488nm. There are other items they list as multiline 458-515nm that have SL in the model # but I believe they are mistaken and are just reading the warning label...
I completely agree with you, my statement about that was referring to the design of DTR's module was not intending for the back half to be the primary heat conducting surface, not laser diodes in general. I agree that the DTR modules should have been designed with a 9mm contact diameter rather...
There are some confusing parts of your post.. DTR's module is also 'full copper' and by designating your 30mm module as 'full copper' you are in a way suggesting to the reader that DTR's is not.
There are two halves to each module. You appear to only be measuring the contact patch of the back...
I remember just a few years ago that diode cost like $2K
Edit- Yikes, looks like their going rate today is $635, I guess having slightly higher beam quality than the Sharp diodes would have to be worth that premium.
I was on LaserTack's site earlier today and they have some of those preproduction Sharp units at 495nm for something like 140 Euros, expensive but it's the first I've heard of those rare wavelength Sharps being sold in a long time.

Thank you! Now I'm curious about how the NUBM0C compares to the JLD480. Also, is the JLD480 really the NUBM0G? It seems to have the same or similar specs and is also just hitting the market.
Any chance you would do a divergence comparison between that new diode and your nubm07 with a given lens, like a g8 or a g2? I dont know if using that gball adapter is going to mess up results unless the same adapter is being used on both diodes, though.
Now that is just sick, beautiful beam... Depending on the cost of the new diode I may just get an NUBM0C like I had planned on months ago but I scrapped the idea when someone said the divergence was WORSE than an NUBM44 and something about the color being less beautiful (??) than an 07 but it...
