# 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:
