我们模拟了一个100太瓦级的光参量啁啾脉冲放大器（OPCPA）系统的设计的一般准则，工作在2.2 μ？> M.基于LiNbO3？>的两级OPCPA系统晶体的数值计算与分步傅里叶变换算法。分析了转换效率和带宽的最大化。系统考虑了时间抖动和泵浦光强度起伏的容限。本文提出的基于OPCPA的理论方案为建立100 TW级中红外激光系统奠定了基础。
We emulate the general guidelines for the design of a 100-terawatt-level optical parametric chirped pulse amplifier (OPCPA) system operating at 2.2 μ ?>m. A two-stage OPCPA system based on a LiNbO3 ?> crystal is numerically calculated with a split-step Fourier transform algorithm. The maximization of both conversion efficiency and bandwidth are analyzed. The tolerance of time jitter and pump intensity fluctuation are considered in the OPCPA system. The theoretical scheme based on the OPCPA present in this paper paves the way for building a 100-TW-level mid-infrared laser system.
