Abstract

Continuous-wave photorefractive experiments in Sn 2 P 2 S 6 crystals and interband photorefraction at the visible wavelengths of 514 and 488 nm are presented. Two-wave mixing and Bragg diffraction measurements at 514 nm show grating response times of around 100 μ s at moderate light intensities of 0.6 W cm 2 , i.e., 2 orders of magnitude faster than measured in the same crystal in the conventional photorefractive regime. A large two-wave mixing gain of up to Γ = 60 ± 8 cm 1 is measured, and holes are identified as dominant charge carriers for the interband photorefractive effect.
