    Default Red 635 is acting up

    Have no idea who is a maker.
    Anyways. I apply 5volts. Diode fires up full power for about a second and then turns off. Sometimes it flickers and then goes off. It has to sit for a few seconds to fires up again but this time only half power. When it sits for about 1 minute it fires full power. What could be? Cold solder on driver board?

    I hired an Italian guy to do my wires. Now they look like spaghetti!

    Update...when it sits off for about 15 minutes then red will run for about 1 minute and fade then go off.

    Dodgy power regulator maybe? it may be that the driver thinks the laser is running at too high a power, so it lowers it untill it is off. then again, I dunno if these lasers have output regulation ...

    Question

    Is it similar to the issue your blue was having? I thought your red was a CNI...

    I think it could be the red from the mystery laser.

    If you need to ask the question 'whats so good about a laser' - you won't understand the answer.

    Well, I was just thinking of whamming the board against the table a couple of times, but if you really want the precision electronic tools, I'd say a 3 lb. sledge would do it..

    Yeah, I think that one's for critical resonator mirror alignment on gas lasers, right?..
