Abstract

We have demonstrated thresholding in a semilinear self-pumped phase-conjugate mirror by introducing grating motion within the photorefractive crystal and using the dependence of photorefractive response time on the intensity of the incident beam. The threshold level I_th was found to be a function of the grating velocity. This property has potential applications in optical computing and optical signal processing.
