WebSecond harmonic generation (SHG) process: (A) energy level diagram, (B) spectral positions of input and output fields, (C) perfect phase matching, and (D) usual wave-vector mismatch in tissue environment, which is compensated by randomness and dispersion. The SHG process originates from induced polarization rather than real absorption.
