【摘要】 对非共线泵浦ＫＴＰ光学参量振荡器的相位匹配过程进行了理论分析和实验研究。结果表明，非共线泵浦双通单谐振光学参量振荡器能够保持其双程增益的优点。使用非共线泵浦的ＫＴＰ光学参量振荡器，在非共线角度超过１°时，仍实现了３１％的１．０６μｍ泵浦光向１．５７μｍ人眼安全激光的能量转换效率。更多还原

【Abstract】 The phasematching condition in noncollinear pump OPO is analyzed. It indicates that round trip phasematching can be achieved if the OPO is in noncritical phasematching at collinear case. Using a KTP OPO, we got 31% of 1.06 μm pump be converted into 1.57 μm eye safe output at a noncollinearity of 1 degree.更多还原
