摘要：

We have for the first time demonstrated two-beam coupling energy transfer at a wavelength of 1.5 μm. Beam coupling gain coefficients of 0.6 cm -1 have been obtained in vanadium -doped CdTe with only 5 mW/cm 2 incident intensity. These gain coefficients exceed typical gain coefficients in GaAs at 1.06 μm wavelength by 50%. In preliminary measurements using the moving grating technique, we have measured a gain coefficient of 2.4 cm-1. Through adjustment of the doping level, CdTe:V can be used as a sensitive photorefractive material through the 0.9-1.5 μm spectral range.
