Discrepancy between the times of space charge grating formation and relaxation in photorefractive crystals
N. A. Gusak Institute of Advanced Training in New Areas of Science, Technology, and Economics, Belarusian National Technical University, Minsk, 220107, Belarus
Abstract:
A discrepancy between the times of formation and relaxation of space charge gratings is found. This effect is observed when the uniform and nonuniform parts of the optical excitation of the medium appear and disappear simultaneously. It is shown that the formation time of these gratings is always shorter than the relaxation time and the higher the light intensity, the greater the discrepancy.
