JLasers - GH04C06V9G TRUE 10W Diode!

Wow! We have a new winner!!!
10 watts of optical output for a $30 USD diode!!!

Behold, the world's most powerful 9mm single emitter multi-mode diode, the sharp 440nm GH04C06V9G.
Beating both Osram PLPT9 450LB_E, and the previously crowned king of power, NUBM0F.
This diode hit a whopping continuous, sustained optical power of 10.2 watts with a G2 lens!!!!
Although this shouldn't be much of a surprise as this diode is rated for 6W as per its datasheet, compared to 5.4W for the 0F

These results were obtained same with all my other tests, using DTR's 25mm full copper module, cooled on a TEC cooler set to 21°C, at 20cm distance from my Sanwu LPM, using G2 lens unfocused just enough to fit fully inside the sensor.

The "WOOO" on the can says it all

Getting 10W out of single diode is crazy. I still have my NUBM44 and that is more than enough.

I'm glad to see that Sharp has this diode. Good for them. I have been a fan of their diodes for years.

Still waiting to find a NUBC31 and/or NUBC32 for sale and find out just how much the can take.

Man, I can’t wait to get my hands on one, I knew it would be a good diode but I didn’t expect 10W!! I wonder how much better the 7W diode will perform??

That would make a great data link through an 8” telescope. Also at 8w it is 444nm which is perfect for Py pumping.
A dual folded end pumped cavity could get 16W pump and likely make 2-3W red. That’s OPSL territory.

https://www.sciencedirect.com/science/article/pii/S0030399222008660 Looks like they got 3.5w from 16w pump into a fiber. Fiber is around 500.00 a meter and you need 1.8M so thi is not a cheap laser.

I’ve got one of these on the way for a build, should be here by the end of the week, I’ll post results asap..

I’ll be using a SXD driver pushed to 5A+, I’m hoping for 9W~ with a G8..

I bought a bunch of these diodes before even knowing what they were capable of. I also just found some X-Wossee BlackBuck 8M drivers capable of 8 amps so I'll be building a badass pointer soon.

DMd on those Black Bucks!!

I've only got a few of them so I'm not really looking to sell them since they're probably some of the last ones in existence.

What a spectacular result! These diodes are now probing the upper limits of what our current crop of “portable” style drivers can manage. Are there any drivers capable of being paralleled to support the increased current demand? I’d like to be able to make a portable using the NUBC31/32 if or when they become available but if I’m not mistaken the switching style drivers we have now don’t play nice with each other in a parallel configuration. And if my understanding of LM338’s in a current regulating configuration is correct, we wouldnt be able to parallel two of those together either.

Has anyone heard from him? I wonder if he might offer a fresh batch? If not I would think it should not be too hard to trace and copy the circuit unless he has a micro like the flex mod
