| Abstract: | In this paper, we report for the first time the a aelfpumped phase conjugate mirror (SPPCM) with reflectance of more than 30 % has been made using photorefrao-tive crystal BaTiO3 grown in China. An experiment to recover a distorted image has been performed successfully using this mirror. Both the built-up process of the self-pumped phase conjugate signal, which depands on the intensity of the incident beam, and the angle between the incident beam and the crystal axis and the erasure rate of the SPPOM have been measured. We report also for the first time a device which can generate bwo or more reflected phase conjugate signals simultaneously for two or more incident beams respectively using only one SPPCM. |
