Non-stationary non-linear polarizing spectroscopy of semiconductor crystals 'for reflection'

Abstract

Gallium arsenide monocrystals have been considered in the paper. The aim of the paper is to study a non-linear optical activity "for reflection" in semiconductor crystals, to develop methods of a high-sensitive polarimetry based on quasicontinuous picosecond lasers. The two-beam non-linear optical activity at reflection from crystals has been revealed, plasma mechanism of a non-linear optical activity has been discovered. Technique and methods of micropolarimetry with picosecond time resolution and sensitivity to an angle of polarization rotation on a microradian level have been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
