Degenerate four-wave mixing in organic azo dyes chrysoidin and benzopurpurin 4B

Appl Opt. 1988 Aug 15;27(16):3418-21. doi: 10.1364/AO.27.003418.

Abstract

Phase-conjugate reflectivity obtained by degenerate four-wave mixing are measured in different azo dye solutions. A reflectivity up to 80% was achieved. Values of the nonlinear susceptibility chi((3)) are calculated, and its origin is discussed.
