摘　　要：对Ar+激光器产生的514.5nm的连续光泵浦KTP晶体的光学参量振荡器(CW-KTP-OPO)做了理论分析,讨论了KTP晶体采用II类临界相位匹配(CPM)时的角度调谐曲线、有效非线性系数以及走离角,并针对所设计的条件计算了KTP晶体的泵浦阈值。合理设计腔内各个器件的参数,最终确定晶体切割角度为θ=67°,φ=0,°此时可以产生中心波长为1.55μm的信号光。A general theoretical of continue wave optical parametrical oscillator that KTP crystal pumped by an Ar^＋ laser at 514.5nm was analyzed. It was discussed that the angle-tuning curve,the effective nonlinear coefficient and walk-off angle when the KTP crystal pumped with the phase-matching of the type- II, the pumped threshold power was counted under this condition. The parameter of the apparatus was well designed, the cutting angle of KTP crystal was conformed θ=67°,φ=0° a signal wave with 1.55 μm center wavelength was presented.
