    Default Creating an 808nm or 1064 nm pointer from a 105

    Is it possible to create a laser with high quality beam by removing the mca or part of it from a lead light. Maybe purchase a replacement crystal.

    Any ideas as to the output with out the green conversion ? How inefficient is this last stage.

    808 to 1064 is about 25%
    1064 to 532 is about 80%

    This assumes a leadlight and the crystals and temperature are "quite good" subtract 10% from both for above-average crystals.

    So Spec, what would happen if you removed the last conversion in a standard pointer ? Would you get 100mw 1064 from a modded 105 and how would this effect the optics, would they work ?

    Hey Gold, Hope all is well

    Im not spec , but since he didnt answer yet, I will..

    I have not tried it yet but would assume it would work ok,
    as long as you remove the output coupler and possibly use
    a different lens ....as the focal length will be different
    It may be possible to get well over 100mw ...
    in fact I would say at least 200mw!!!

    The IR pointers I have made here were direct 785nm 150mw
    diodes ran at 100mw
    Using my own diode housings, It was easier to use and focus.
    it is neat to burn tape and pop ballons with a laser
    with very little visable light..but thats about it for now.

    my idea is to make something useful , like maybe
    a long range remote control for controlling motors and other
    devices I cant reach due to height or other obstructions.
