Abstract
Self-defocusing of ordinary and extraordinary laser beams have been investigated in cadmium sulfide semiconductors in the near-band-edge absorption region. First it has been shown experimentally, that effects of the anisotropy nonlinear refraction induced by charge carriers created by single photon absorption is described whole set components of the third order nonlinear susceptibility tensor. New type of transverse optical bistability with increased amout of feedback due to nonlinear anisotropy was demonstrated.
