JLasers - NUBM0G

[loreadarkshade]

This amazing diode came out a few months ago. It boasts a gorgeous 465-473nm wavelength across its power band.
In addition, it has performed as well as the osram 5W diode, just under the NUBM0F, beating all other tested diodes!

Decanned hitting over 8 watts! This little monster can output a gorgeous 473nm at around 6.2-6.5A and even richer cyan when pushed a bit harder.

Measurements taken with DTR 25mm Copper module, G2 lens, Sanwu LPM-20T, 21°C TEC cryo-block

Shoot dang she’s an angry little diode. Off all the high powered diodes we’ve had over the years the NUBM0G is still the most impressive in my book. Crazy power and a beautiful color

 

[loreadarkshade]

Yup, its performance rivals that of the Osram PLT9 450LB, just under the 0F

NUBM0G comfortably hitting 473nm at 6.0-6.5A

Measurements taken with DTR 25mm Copper module, G2 lens, Sanwu LPM-20T, 21°C TEC cryo-block

This diode can peak at 478.6nm @ 7.5A
I will update this thread with a graph showing wavelength relative to current and optical power

Is that stable at 477-478nm or it is on the edge of decline?

Way past the foldback point, sadly. But 473nm which is a rare exotic color is very reasonable!

Handy graph. Very good for anyone that wants a high power 473nm diode.

High power is right, the NUBM0G is so far the best option right before the 0F, beating all other diodes in efficiency/power.
Even beating the NUBM47/44, and Osram PLPT9 450LB

I absolutely like the way you test new diodes and when you use a power meter and spectrometer for building laser pointers.
That will help you to make sure for instance that a 488nm laser you build will be exactly true 488nm cyan color, not 490nm or 485 nm since these wavelengths are not true cyan.
It's definitely worth letting your customers receive their desired wavelengths and power outputs
