    That aom will do 532nm, and all the wavelengths listed,
    check this experiment out:

    do a search for "AA.MTS.110/A3-VIS"
    Cheers

    its funny you bring this up now i just tried this for the first time last
    night and it dosent seem to work when i give it some voltage from a dac or even a 1.5v battery i get this pattern with no voltage i just get a normal unaffected beam

    Hi,
    Do you have it on a mount?
    It needs to be aligned perfect, sounds like it doesn't have the correct bragg angle

    Take a look at this: http://opto.braggcell.com/uploads/fi...EORY-NOTES.pdf

    what is the size of the beam going into the aom, is it hitting the sides of the aperture? Don't think the cross like parttern is right tough.
    check this setup by IfShrad of the same modulator on youtube: http://www.youtube.com/user/lfShrad#p/a/u/0/fQmp-p7i4u8
    Shrad is a member here on PL, if he sees this maybe he comment.

    If you look here you'll see he has the 'atom' patterns too. So I think it's inevitable. But what it is caused by, I don't know.
