摘要：

We report on the photorefractive properties of a Cr-doped (K1-xNax)2A-2 (SryBa1-y)2-ANb10O30 (x = 0.586, y = 0.659, A = 1.12) single crystal in the near-infrared spectrum. The sample exhibits photorefracitivity for wavelengths up to at least 840 nm where the steady-state two-beam coupling gain is found to be larger than 2 cm-1. Photorefractive gain and decay rate are measured as a function of wavelength, grating spacing and intensity. The wavelength dependence of gain fluctuations in two-beam coupling are also measured.
