摘要
本文通过检测BaTiO_3晶体的二波耦合增益系数P和自泵浦位相共轭反射率R对随入射角的变化关系,经过理论分析指出R的角度依赖性是P的角密依赖性的结果;详细地解释了全内反射自泵浦位相共轭的双区域耦合理论,指出位相共轭输出的频移特性是泵浦光在双区域间“振荡”的结果;并解释了自泵浦形成的阈值特性。
The angle dependence of the self-pumped phase conjugation (SPPO) reflectivity is regarded as a result of the angle dependence of exponential gain TWM in BaTiO3 crystal through measuring and analysing. The theory of double-region coupling of SPPC is explained in detail by using total internal reflection at a corner. It ia pointer that the frequency shift resulted from pump light oscillation between the two interaction regions. The threshold property of forming the SPPC is presented.
