| 摘 要： | 对非共线Ⅱ类相位匹配的ＫＴＰ飞秒光学参量振荡器进行了分析和理论研究，用数值方法得出参量增益的变化曲线和参量光的光强分布，与共线相位匹配相比，非共线方案具有更高的参量增益，更好的光束质量，特别适合飞秒光学参量的振荡器。

| Abstract: | The KTP femtosecond optical parametric amplification in type Ⅱ noncollinear phase matching configuration has been investigated. Parametric gain and optical intensity distribution of signal has been obtained by numerical method. The results show that parametric gain is higher and the beam quality is better in noncollinear phase matching configuration than in collinear phase matching. It′s more suitable in fs optical parametric oscillator (OPO). |
