Second harmonic generation (SHG) investigations of different phases of banana shaped molecules

Pages 341-347 | Received 01 Sep 2001, Published online: 06 Aug 2010
 

Abstract

New liquid crystals consisting of non-chiral, banana shaped molecules are investigated by the generation of the second harmonic (SHG) of an optical wave. The temperature and electric field dependence of the SH activity of the apparent thermodynamic phases of several homologues are studied and first quantitative values of the effective non-linear optical coefficients are given.
