The spectroscopic and non-linear optical properties of photorefractive semiconductor materials based on cadmium telluride (CdTe) doped with V, Ti, and Fe are investigated. Non-linear optical properties have been studied on the base of four-wave mixing geometry at the wavelength of 1.06 µm and pulse width of 10 ns. Recording of dynamic grating in the absence of an external electric field was realized with the diffraction efficiency up to 2 lifetime was found to be practically independent of the dopant and amounts to 200 ns.
