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.
