摘要: 通过对非线性三波耦合方程组进行数值求解，研究了光参量放大的增益特性及饱和放大特性。给出了泵浦光、信号光参数对参量增益的影响及其与晶体饱和长度的关系。且OPA具有传统CPA系统所不具有的优点，将有可能取代传统的CPA系统而作为超短超强激光系统的新型前端。Abstract: Theoretical analysis and detailed numerical simulation on optical parametric chirped pulse amplification(OPCPA) are presented in this paper. We obtain the character of optical gain and saturation amplification under different conditions of pumping beam and signal beam. Also a design example of OPCPA and it’s calculated result are given.
