Abstract

The photorefractive properties of Bi2TeO5 crystals were measured with the wave mixing technique using the 532 nm output of a Nd:YAG laser for writing gratings. The saturation diffraction efficiency of the grating for the optimum crystal orientation and beam polarization configuration exceeded the 40%. Above a threshold write intensity, a remarkable fraction (10-20%) of the saturation diffraction efficiency remained stable for several days in the crystal. A weaker read beam of the same wavelength did not erase the grating. A two-dimensional holographic image was also written into the Bi2TeO5 crystals for the first time.
