Abstract

Using 532-nm, 30-ps pulses from a pulsed Nd:YAG laser, we measure high speed two-wave mixing in organic liquids such as carbon disulfide, semiconductor glasses such as CdS_xSe_1-x in a borosilicate matrix, and metallic colloids such as gold particles in a water or glass suspension. Since these materials are all isotropic, all multiwave mixing processes are by necessity due to third- or higher-order nonlinear electric susceptibilities.
