Abstract

A new method is proposed for determining the two-beam coupling gain coefficients of photorefractive crystals with both <i>o</i>- and <i>e</i>-polarized lights. This method enables one to determine simultaneously and precisely the gain coefficients of a crystal for <i>o</i>- and <i>e</i>-polarized lights while the fanning effect is diminished. Experimental demonstrations are presented.
