Nonlinear Optical Responses and Laser Damage Thresholds of Films of a Polarized Stilbene Side Chain Liquid Crystal Polymer and a Phthalocyanine

Abstract

Thin films of a side chain liquid crystal polymer (P-10) with a 4- dimethylaminostilbene-4'carboxylic ester mesogen were measured to have degenerate four wave mixing efficiencies at 532 nm 18 times that of carbon disulfide and 0.55 times that of a film of 1.5 weight percent 4-dimethylamino- 4'-nitrostilbene (DANS) in poly(methyl methacrylate) PMMA and second harmonic generation efficiency at 1064 nm 0.17 times that of a film of DANS in PMMA. A film of 2.0 weight percent of octakis(2-ethylhexyloxy)phthalocyanatocopper(II) in polystyrene was measured to have degenerate four wave mixing efficiency at 532 nm 19 times that of carbon disulfide. Single shot and cumulative laser induced damage thresholds were measured for all three materials at both wavelengths. (AW)
