摘要：

We have studied the various nonlinear optical processes that can be described by a fourth-rank chi(3)-tensor: signals of frequency omega in degenerate four-wave mixing (DFWM), harmonics of frequency 2-omega and 3-omega, and chi(3)-type difference-frequency generation (DFG) with observation of anti-Stokes emission of a signal of frequency 2-omega-1 - omega-2. Structural information in terms of normalized anisotropies is derived in all frequency domains by analysis of the elements of the respective orientation-dependent susceptibility tensor. A novel laser-based technique for the remote orientation analysis of crystalline structures is introduced.
