Abstract
We have studied the various nonlinear optical processes that can be described in terms of a third-rank (chi) (2)-tensor or a fourth-rank (chi) (3)-tensor: signals of frequency 2(omega) as in second-harmonic generation due to (chi) (2), and signals of frequency (omega) , 2(omega) , 3(omega) due to (chi) (3). (chi) (3)-type difference-frequency generation is also discussed. Structural information is derived in all frequency domains by analysis of the elements of the respective orientation dependent susceptibility tensor.
