Abstract
Laser-induced generation of second- and third-harmonic radiation is studied in cholesteryl nonanoate and in other cholesteric and nematic liquid crystals. No second harmonic is observed in any of the liquid-crystal mesomorphic phases, indicating their ordered molecular arrangements to be centrosymmetric. Large changes in third-harmonic intensity occur at several phase transitions, and their possible origins are considered.
