    Default Mix Infrared and visible green Laser...

    Hi everybody,

    I am quite new in Lasering and would like to know what
    will happen if one set up a typical DPSS green Laser without
    any filters.

    I guess it will result in a mix of 808, 1064 and 532 nm ?!?

    Will the final optics be able to collimate this "mix" or will
    only the green be focussed and the IR-light will escape??

    I wonder if it is possible to create a Laser of a total power of
    lets say 500mW, where the green-power is only 5 or 50 mW..

    To say, green will act as a pilot-laser and the real power comes
    from Infrared...
    Just for cutting things, I guess this might be the perfect solution
    (if Physics does not bless me :-)

    A green DPSS laser pointer has just one IR filter, removing it would result in a total output increase but it would not be possible to collimate both 1064 and 532 wavelengths at the same time. I do not know if 808nm is involved in the output increase. Read the post concerning the IR pointer.
    Surgical lasers use a visible guide laser and IR laser. There is a post made here recently, it shows how a green DPSS works.
