Demonstrated is the hologram fixing in potassium lithium tantalate niobate (KLTN) by photorefractive domain switching. KLTN is a photorefractive material with a perovskite structure. In the experiments, a monodomain sample with a phase transition at 25°C is used. The sample is 7 x 6 x 2 mm, cut along the crystallographic axes, polished optically, and had electrodes evaporated on the 2 x 6 mm faces. Experiments are performed on a stable temperature mount enclosed in a vacuum chamber. These experiments suggest that it may be possible to use high Tc KLTN crystals for long-term storage of optical holograms fixed by domain switching.
