| Abstract: | Authors deduce the formula of specular reflectivity from photorefractive phaseconjugate mirror as a function of conjugate reflectivity and gain-length product. The measure results of specular reflectivity from self-pumped BaTiO3 crystal versus the conjugate reflectivity and incident angle are given. The diffrent effects of specular reflectivity between two classes of photorefractive phase-conjugate mirrors are analysed by means of the formula. |
