摘要
给出了一种ffner型展宽器的原理和设计,在光线追迹法的基础上用Matlab辅助程序进行了数值模拟计算,得到了影响展宽器性能参数的直观图形,并对这些参数如何影响展宽器的性能进行了分析讨论,最后给出了用于OPCPA展宽器的最优化设计参数.结果表明这种展宽器能将15fs的脉冲展宽到900ps.
The theory and optimized design of a kind of Offner stretcher is presented. After stimulated numerically and calculated with Matlab assistanted program based on ray tracing, the direct graph about parameter related with stretched capability of the stretcher is gained. Analysing and discussing that how these parameters affect the stretching capability, the optimized parameter in OPCPA stretcher is presented, the results show that the stretcher in this paper can stretch 15fs pulse to 900ps.
