Sum-frequency generation
text:
Sum-frequency generation (SFG) is a second order nonlinear optical process based on the mixing of two input photons at frequencies ω 1 and ω 2 to generate a third photon at frequency ω 3 . As with any χ optical phenomenon in nonlinear optics, this can only occur under conditions where:
the light is interacting with matter, that lacks centrosymmetry;
the light has a very high intensity.
Sum-frequency generation is a "parametric process", meaning that the photons satisfy energy conservation, leavi
