INCOHERENT-TO-COHERENT CONVERSION IN A PHOTOREFRACTIVE CRYSTAL

摘要

The properties of coherent output images for incoherent - to - coherent convers ion in a photorefractive crysta1 were theoretica1ly investigated based on a two-dimensional model. The results indicated that the properties depend on the intensity ratios of beams, the length and coup1ing coefficient of the crystal, as well as the incident direction of the incoherent image.
