Abstract
Photorefractive CdTe:Ge crystals are studied as a medium for laser ultrasonic detection at 1.06 µm and 1.55 µm. The complex coupling strength is estimated for the two-beam coupling configuration in the presence of a dc field. Excellent performance of the material is shown at both wavelengths by demonstration of high sensitivity and high cutoff frequency at low intensity. Different adaptive interferometers based on two-wave mixing, polarization self-modulation and vectorial wave mixing are realized in the same crystal. The sensitivities of these interferometers are compared.
