| 摘 要： | 利用(KNa)_(0.1)(Sr_(0.75)Ba_(0.25))_(0.9)Nb_2O_6掺Ceα面斜切晶体实现了无外场、无外反射镜、无外加泵浦光束自泵浦连续波位相共轭,其相共轭反射率达25％,阈值功率小于0.03w/cm~2。并首次摸拟了其光折变耦合系数与晶体α面斜切角的关系。

| Abstract: | Self-pumped phase conjugation in a-face titled-cut Ce-doped (KNa)0.1 (Sr0.75Ba0.25)0.9Nb2O6crystal was demonstrated without external reflection mirrors, pumping beam and applied field, and phase conjugation reflectivities as high as 25% were measured. The threshold power was lower than 0. 03 W/cm2. Its photorefractive coupling constant was computed for various a-face titled-cut angles for the first time. |
