Would it be possible to produce a dif laser by 382nm UV diode laser with a 910nm IR

    What would prevent this from being feasible 910nm-382nm-=528nm?????

    Other wavelengths are produced by taking the sum or difference of the frequencies, or of 1/λ.

    So using 910 nm and 382 nm:

    1/382 - 1/910 = 0.001519
    and
    1/0.001519 = 658

    So this would produce light at 658 nm. However, there must also be a nonlinear crystal that would work at these wavelengths, and I am not sure if that is the case.

    :surprised how would you combine two beams. Using optics or electronics.

    Thanks alot

    Using optics, specifically a "mirror" that reflects one wavelength and transmits the other. For an example, see the final figure at the very bottom of the page here:

    The element just to the left of "DFG" is where the two laser beams are combined; the Tunable Laser beam is reflected, and the Nd:YAG beam is transmitted. The difference frequency beam is created within the DFG crystal.
