Thread: The smallest 445nm 4W blue laser in the world -LASEVER

  1. Default The smallest 445nm 4W blue laser in the world -LASEVER

    Following the 638nm 1W red laser, the 445nm 4W blue lasers come on to the stage! The beam size is 4x2mm, divergence is 1x0.4mrad. They have TEC (pertier cooler) inside the modules, so that the stability and life time are ensured.
    Anyone interested please feel free to consult with me.

    Hi David,
    What kind of diode are you using, is it a single diode?
    Beam specs are very good, is the divergence half or full angle?

    If I had to guess, I would think it was maybe one of these, corrected. http://www.photonlexicon.com/forums/...003#post291003

    Mmm not sure as they have no good divergence at all...

    You are right. It is not a single diode.
    The divergence is full angle. The beam size is 4x2mm near aperture, 18x6mm at 14 meters. The horizontal divergence is (18-4)/14=1 mrad.
    Thanks,
    David

    If you could manufacture a module with a corrected beam and good divergence there would be a bigger market here.
