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 Ith was found to be a function of the grating velocity. This property has potential applications in optical computing and optical signal processing.
