This technique involves the phenomenon of wave mixing, takes advantage of the high intensity of stimulated Raman scattering, and has the applicability of conventional Raman spectroscopy. In the CARS method two strong collinear laser beams at frequencies ν1 and ν2 (ν1 > ν2) irradiate a sample. If the frequency difference,...
