Abstract
The LiTaO 3 crystal doped with 0.03 wt% Fe 2 O 3 was grown in a diameter-controlled Czochraski equipment using Si-Mo bar heater furnace. The photo-damage resistance ability, exponential gain coefficient, diffraction efficiency and response time of Fe:LiTaO 3 and Fe:LiNbO 3 crystals were measured. The measured results showed that the photo-damage resistance ability of Fe:LiTaO 3 crystal was as much as 5 times higher than that of Fe:LiNbO 3 , the response speed of Fe:LiTaO 3 crystal was improved one order of magnitude than that of Fe:LiNbO 3 , and the exponential gain coefficient and diffraction efficient of Fe:LiTaO 3 crystal were smaller than that of Fe:LiNbO 3 , respectively. Using Fe:LiTaO 3 crystal as recording medium, the obtained image was clear and complete in the holographic associative memory experiment using self-pump phase conjugate reflector.
