| 摘 要： | 理论研究了BBO晶体在Ⅰ型相位匹配下非共线情况时的激光参量放大特性。研究结果表明 ,对于一定波长的抽运光 ,存在一定的非共线入射角对应一定波长的信号光 ,使在较高的激光增益下增益带宽最大 ,同时温度的调谐也对增益谱的形状有部分影响。这对于短激光脉冲的激光参量放大的优化具有重要意义。

| Abstract: | The non collinear optic parametric amplification using BBO crystal with type Ⅰ phase matched geometry is investigated theoretically. For the certain pump wavelength and signal wavelength, it is indicated that the non collinear incident angle exists with the maximum gain bandwidth and the higher gain. The temperature also effects the gain spectrum partly. The theoretical analysis is useful to optimize the optic parametric amplification of the short pulse. |
