Abstract

In this work for the first time the light induced phase transitions in amorphous As-S compositions in periodic interference field have been studied with the help of holographic method, offered by us earlier, which permits us to carry out independent measuring of absorptivity ((Delta) (alpha) ) and refractivity ((Delta) n) changes in studied materials in bulges and nodes of interference pattern. It is shown that stable high-temperature (T approximately 100 degrees Celsius) transitions happen due to a D degree(s)-centers diffusion from bulges of interference pattern to nodes. The disturbance of thermodynamic equilibrium distribution of defects (D-centers) resulted in a diffusion of D degree(s)-centers in the case of As₂S₃.
