Abstract

The self-induced rotation of the plane of light polarization of the pulse ruby and neodymium lasers was studied as a function of value 2hv-E_g in CdP₂ and ZnP₂ single crystals. This phenomenon is known as nonlinear optical activity (NOA) in crystals which have a pronounced two-photon absorption of the laser radiation of the investigated wavelengths. intensity of the pulse laser radiation transmitted through crystal and analyzer plotted against intensity of the radiation incident on crystal has a nonlinear character because of both the display of the two-photon absorption (2hv greater than E_g greater than hv) and the self-induced rotation. These results offer to the determination of the specific value of NOA. The temperature dependence of the specific value of NOA and its dependence from intensity of the laser radiation are determined. The likely mechanisms and application of the investigated phenomenon are discussed.
