Laser Induced Phonons (LIPS) in MBE Grown ZnSe

Abstract

Thin film ZnSe, grown by the MBE method, has been examined using the technique of degenerate four wave mixing, DFWM, using laser illumination at 532nm. Laser induced phonons are observed in this thin film material but are not seen in a sample of bulk polycrystalline ZnSe. This observation of laser induced phonons is the first reported in ZnSe.
