INTRACAVITY FREQUENCY DOUBLING TECHNIQUE THROUGH MICHELSON INTERFEROMETRIC NONLINEAR COUPLED CAVITIES

本文描述使用迈克尔逊干涉仪非线性耦合腔的内腔二次谐波产生(SHG)的新方法.在KTP晶体中获得65%的平均内腔倍频转换效率.推导关于这些耦合腔的非线性矩阵微分方程式,能计算出增强倍频转换效率公式.与其他理论和实验结果的简明比较,证明本方法在理论与实验之间有较好的符合.

A new method of intracavity second-harmonic generation ( SHG ) in the Michelson interferometric nonlinear coupled cavities is described and an average intracavity doubling conversion efficiency of 65 percent in KTP crystal is achieved. A nonlinear matrix differential equation for those coupled cavities is derived and the enhanced frequency conversion efficiency formulas are calculated. A brief comparison with other theoretical and experimental results demonstrates that this method has shown greater agreement between theory and experiment.
