Abstract
The simple graphic treatment of the thermostimulated photorefractive grating erasure data has been proposed in purpose to determine some important photorefractive crystals parameters. The theory was based on the process of nonisothermic relaxation of photorefractivity under temperature increasing by taking into account the main feature of the photorefractive gratings, namely, the photorefractive electric field modulation which period is equal to one of the recording pattern.
