我们提出了数值和实验研究的前端激光系统播种亚皮秒多太瓦/拍瓦光源的基础上两个高度饱和的光学参量放大器。数值结果显示能量增益,光谱增益,和稳定性接近饱和。实验实现的系统已经建成,其性能已被发现是在良好的协议与数值模拟。在几个皮秒增益窗口内,总增益超过105,脉冲能量为100 μJ,均方根稳定度为4%。
We present numerical and experimental studies on a front-end laser system for seeding a sub-picosecond multi-terawatt/petawatt light source based on two highly saturated optical parametric amplifiers. Numerical results showing energy gain, spectral gain, and stability as saturation is approached are presented. An experimental realisation of the system has been constructed, and its performance has been found to be in good agreement with the numerical simulations. The total gain is in excess of 105over a few picosecond gain window, and the pulse energy is ∼100 μJ with 4 % root mean square stability.
