    Shit man; it is broken... that last diode on the left, "front row" looks more like an LED than a laser...

    Default rebuild

    I say rebuild it and get it scanning at the next lem
    f**k arctos, they can come see it
    you are not making money from its use.
    Icould always do it for you I am bored and have nothing on for the winter

    its not broke, its just a brought a milling machine so wana redo a few parts.

    i will rebuild it, but sadly my new house comes before lasers at the moment.

    i may get it scanning before the next meet

    Then why not add a block with 4 Blue diodes + prisms to the setup then you can have a 9W Purple beast

    Default Question

    Do they not correct the Divergence before the telescope? Most of the diodes have WAY worse divergence in one axis. So if they just go through the telescope for example a diode with a .5 x 1 mrad through the 3x would become 1.5 x 3 mrad but a smaller initial beam. Or am I missing something. Just wondering how they are able to keep the divergence to 1mrad after a 3X tele?

    When you compress different sources into one beam you can get as low divergence as the crappiest source. As long as initial sources are focused to infinity and diodes are giving the best beam by themselves I can see no big problem making a very good beam.

    You can do telescope and reverse telescope. One will have a fat initial beam and then slowly gets to a focus point and after that gets bigger again. The goal of this is to put focus as far as possible. And you don't really need more then 300m anyways for lasershow. Or have a flashlight effect. Initial beam is very small but gets bigger over the distance. I have to use the last way on my 1.2W 635nm because I have 3mm galvos. I tried other way but I'm getting 8mm initial beam. Doesn't fit on 3mm galvos.
    I hired an Italian guy to do my wires. Now they look like spaghetti!

    Really great work Andy!

    Out of interest, would there be any advantage to stacking the individual beams closer together? From the photos there looks to be a small gap between the beams.

    thats really really sexy...

    also, doesn't the ca$io have 24 diodes? that rig uses 24 diodes... you see where this is going?
