Paper Abstract

We report the effective excitation of space-charge waves (SCW) in photorefractive ac-biased CdTe:Ge crystal illuminated by a laser beam (λ = 1150 nm) and an auxiliary incoherent light with different wavelength. We show that laser beam scattered from SCW has resonant dependence on the auxiliary light wavelength. The effect of auxiliary illumination on photorefractive two-wave coupling and subharmonic generation is presented.
