摘要
为了在高能拍瓦激光系统中设计和应用光参量啁啾脉冲放大(OPCPA)技术,建立了仿真模拟程序,并以周期极化LiNbO3光参量放大器为例,分析了在准相位匹配条件下,前级光参量啁啾脉冲放大特性的影响参数,包括:非共线角、晶体长度、增益带宽、高阶非线性效应等。为设计与应用光参量啁啾脉冲放大技术提供了理论和数据上的参考。
Abstract
A simulation program is finished for applying the optical parametric chirped pulse amplification (OPCPA) technique to the high energy perawatt laser system. Taking periodically polarized LiNbO3 optical parametric amplifier as an example, the influence of noncollinearly angle, crystal length, gain bandwidth and high-order nonlinear effect on the front end OPCPA under quausi-phase matching conditions is analyzed. This work provides theoretical and experimental reference for the design and application of OPCPA.
