    It doesn't work guys... You kinda get it in graphics, but not in beams. 405+532 doesn't give you blue, and 473+405 doesn't give you deep blue. 405+a bit of 473 and a bit of red will give you a nice purple, but that' is not a "wavelength"... Just a purdy color.

    You can always mix a bit of green iwth the violet to give you blue though....

    BTW, I'd be interested to know how it is that medialas get 600mw of 445nm after optics out of a 500mw rated diode.
    the medialass DLR 350 diodes are also overdriven.
    the have 2 diodes running in series combined using a pbs and one mirror.
    the use mitsubishi diodes in these and there only rated for 120 mw cw per diode
    As far as i know there are no 5.6 mm 200 mw cw rated diodes available at 655nm
    Do not look into laser with remaining eye
    Need laser repair contact me !!!!!!

    Coordinates in CIE xyz: 0.1392 0.0569 0.8039
    Si if I understand correct, adding 200mW of 405nm to 100mw 473, will only give you about 10% more visible beam?
