Abstract
The influences of iron doping on the photorefractive properties of KTa 1-xNaxO3 (KTN) crystals were studied. The two-wave-mixing gain coeffic ients and the grating formation rates were measured in undoped and Fe- doped KTN samples. Photorefractive parameters, such as the effective c arrier number density, were determined for these samples. It was shown that the gain coefficient increases significantly with the doped Fe c ontent, but the grating formation rate decreases with it, and that all the influences of iron doping originate mainly from the variation of the effective carrier number density.
