摘　　要：介绍了新近提出的光学啁啾脉冲参量放大技术 ,并以高增益、宽谱带的双轴非线性晶体LBO为例 ,研究了抽运光和信号光的相位匹配角的关系、增益、增益带宽、匹配角的选择 。The technique of optical parametric chirped pulse amplifier proposed recently is introduced, and some characteristics such as phase match angle, gain and bandwidth are analyzed taking LBO crystal as an example. In addition, the dependence of the gain varying with length of the crystal is studied, and the transforms of the pulses after amplification with sech 2 and Gauss shapes are given.
