For public info / archives: Repaired/disassembled a Sanwu Pocket 505nm 50mW today. Driver is using the LT1931 Inverting DC/DC Converter, which was faulty and overheating on this board, causing a blink after long runtimes. Their driver seems to be set to 400mA CC at the diode. They are using a...

He is talking about my C3 700mW 520nm. It pulls around 2.2A from the battery, as it is a boost driver and needs more amperage to push 1.7A to the laser diode. 3A was just to be conservative :)

Thank you. I've worked very hard to get a finalized design that works. They are not It is built around the SingFire SF-348 flashlight host, with a driver and pill designed by myself to adapt 5.6mm and 9mm diodes as well as a lens

$130 USD LIMITED QUANTITY https://www.jlasers.org/handhelds/nano-series/nano-520nm-500mw Uses 1x 10440 3.7v li ion button top I can also do up to 550-1000mW without warranty (VERY short duty cycle, risk of heat damage) I can also do 1-500mW free of charge upon request

Wow! This diode is incredible. Not in power, but in wavelength. Not to mention this diode is a brute, taking a whopping 7.7 Amps before folding back to 50mW. 470nm at 5.0A 473nm at 6.5A 475nm at 6.8A Finally, at 7.7A, this diode emits a GORGEOUS 480.7nm blue :O To my eyes, this was a stunning...

Here is a sweet little graph between Nichi@'s 465nm diode lineup, comparing the 07, 0C and 0G in terms of power and color. It's interesting to note that the 0C is able to take much more abuse, therefore have a more dramatic wavelength shift all the way up to 480nm at 7.7A !

They do this because allowing for slow cheaper shipping options lead to too many customer complaints

⬅ Other Diode Tests Here are the test results for the NUBM08. You can purchase this and other diodes on my store. Here are the results: (decanned and using G2 lens of course, as with all other diodes)

I hope they will serve the community well! These tests took forever

⬅ Other Diode Tests Here are the test results for the NUBM06. You can purchase this and other diodes on my store. This one's results were surprising in terms of power. It surpassed most mid-tier diodes

The beam is extremely tight and concentrated :) Very good for star-gazing!

⬅ Other Diode Tests Here are the test results for the NUBM0E. You can purchase this and other diodes on my store.

Very cool! Thank you I wanted to order some yellow sticky paper for my laser printer to try this

I am only measuring the beam width (the high brightness part of the focused line)

You were correct in that the 2E lens clips off the NDB7875 fast axis! Remarkable. This is new to me. The G2 lens does not since it focuses so closely However my divergence measurements were equivalent with the G2 lens as with the 2E lens Real measured divergence...

I meant crystals as in the gallium nitride semi-conductors I see! Oh boy, I hope youre wrong so I dont have to run all those tests again 😅 Ill try this later with 3 diodes and see what we get :)

yess

Oh yes I plan to test all high powered greens. Not sure about violet or red yet, maybe in time

⬅ Other Diode Tests Here are the test results for the NUBM0A. You can purchase this and other diodes on my store. Very good power from this one ! 6th best diode in the line-up so far. The divergence is nothing to write home about though..
