In testing involved the following laser diodes:
1- 9mm 445nm Laser Diodes
2- Nichia NDB7675 1.4W 462nm Laser Diodes
3- M462 462nm Laser Diode
4- Osram 1.6W PLTB450B 450nm Laser Diodes
Medium temperature of ~ 30 degrees.
Maximum current of 1.4 amps

Spectral analysis of the blue laser diodes!

Very nice and thank you Denito! From what I could make out, it looks like both the 462's were right on spec. Is that what you saw? I couldn't make out some of the numbers, my monitor is a little fuzzy

Can please I ask what software and sensor you are using? Would that setup be capable of testing diodes for single longitudinal mode operation?
I've been thinking about keeping my eyes open for a scanning Fabry Perot...
