摘要
讨论了双轴晶体中参量过程的角度匹配计算方法,计算了KTP晶体对于355、532nm和1064nm波长泵浦的光参量过程的角度匹配曲线;对于三个主平面内的Ⅱ类相位匹配曲线的特点作了分析和讨论。实验验证了532nm波长泵浦的光参量过程,在X-Z平面内的Ⅱ类相位匹配角度值与理论计算的结果一致。
The calculation method 01 angle phaae-matching for optical parametric generation (OPG) in biaxial crystals was presented. The angle phase-matching curves and their characteristics of OPG in KTP crystal pumped by 355nm, 532nm, and 1064nm radiation were calculated and analyzed. Our experimenis have confirmed the optical parametric generation pumped by 532nm laser output, which is in agreement with the calculated curves for angle phase-matching of type II in X-Z plane.
