Abstract

By all-optical poling of a medium the long-lived space-periodic electrostatic field arises inside the sample and, as a result of such photoinduction, an isotropic medium gains the properties of an inhomogeneous optical single-axis crystal with the existence of the periodic &pchi;⁽²⁾nonlinearity. In this paper the results of the investigation of the temperature influence on the all-optical poling process and on the kinetics of the formation of induced gratings &pchi;⁽²⁾in optical multi-compound phosphate glasses are presented. The experimental investigatation of the all-optical poling process during the smooth variation or the step changing of the temperature of studied samples demonstrates the anomalous behavior of the process of the formation of the &pchi;⁽²⁾ nonlinearity in medium and shows the existance of the region of the critical temperature in which the sharp change of the kinetics of the all-optical poling process takes place. The study of the kinetics of the anisotropy in near critical region shows the possibility of the increase of the efficiency of all-optical poling in glass media by means of the high-temperature influence.
