Abstract

The second harmonic generation (SHG) of liquid crystalline main-chain type polymers were investigated. The sample polymer is a copolymer of 2-hydroxy-6-naphtoic acid with 4- hydroxy-benzoic acid, in the composition ratio (equals 30/70). The nonlinear optical coefficient d_exp of the samples prepared by mechanical extension at the liquid crystalline temperature is about 5 pm/V. Quasi-Phase Matching seems to be performed by piling the mechanically oriented thin films with alternatively directed machine direction. More than 8 times SH intensity value of that for 1 sheet of film was observed. For this trials, films being immersed in equal refractive index liquid crystals were used.
