Abstract

We report experimental results on the photorefractive properties of chrome-doped GaAs. Grating-formation time and the behavior of the two-beam-coupling gain as a function of intensity, grating spacing, and applied voltage have been investigated. Gains as high as 0.9 cm⁻¹ have been observed with 6-kV voltage applied.
