Paper Abstract

The polarization state of light-gated phase conjugate beam in a methyl-orange doped polyvinyl alcohol film was investigated for various polarization configurations of pump and probe beams. Circularly polarized light emitted by an argon-ion laser at 515 nm was used as a gating beam for uniformly exciting randomly oriented methyl-orange dyes, and a krypton-ion laser light at 647 nm was used for degenerate four-wave mixing process. Experimental results agreed well with theoretical results, which obtained by assuming that the methyl-orange doped polyvinyl alcohol file is optically isotropic. From the comparison between experimental and theoretical results, we obtained the tensor of nonlinear optical susceptibility (chi) 1221equals0 at a wavelength of 647 nm in the presence of the gating light.
