    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

    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?
