Paper Abstract

Experimental results on ultraviolet photorefraction in nominally pure and iron doped (alpha) -LiIO3 crystals are presented. At room temperature two time constants and a characteristic minimum are observed in holographic erasure experiments. With decreasing temperature the maximum diffraction efficiency rises by two orders of magnitude. These features of the erasure kinetics and temperature dependence are explained by a theoretical model taking into account only electronic photoconductivity and ionic conductivity.
