Abstract

Photorefractive semiconductors, with their faster response speed than oxide materials, are attractive candidates for a variety of applications ranging from image processing,¹ holographic storage,² to optical beam combining. Cadmium telluride crystals doped with vanadium atoms have been shown to have the best sensitivity among known semiconductor photorefractive materials. With manganese as the new co-dopant along with vanadium, high photorefractive two-wave mixing gain was observed at the optical wavelength of 1.064 µm in the absence of applied electric fields.
