Abstract :
The effect on the photorefractive and optical properties by varying Cr and Mo dopant concentrations equally in co-doped SBN:60 is investigated. We report the effect on the absorption, two-beam coupling, speed of response, and diffraction efficiency. From these measurements the role of the donor and acceptor density is determined
