为康普顿X射线实验开发了高稳定高能量飞秒激光系统。该激光系统以啁啾脉冲放大为基础,并且每个部件都是主动或被动稳定的。主振荡器时间抖动小于100fs,两个独立的振荡器相对时间延迟300fs。开发了测量低重复率放大脉冲时间起伏新技术,以及特殊设计的高光束质量再生放大器。根据实验结果提出了供直线对撞机用的新技术方案,包括瞬态矩形脉冲技术,它用于低发射度电子发生器;供CO_2激光放大器用的时间稳定的籽源;以及供γ-γ对撞和多群聚电子发生器用的多脉冲高能激光器。
Developed a high stability and high energy femtosecond laser system for Compton X-ray experiments. The laser system is based on chirped pulse amplification and each part is actively or passively stabilized. The main oscillator time jitter is less than 100fs, the two independent oscillators relative time delay 300fs. New techniques have been developed for measuring the timing of low repetition rate amplification pulses, as well as specially designed high beam quality regenerative amplifiers. According to the experimental results, a new technology scheme for linear collider is proposed, including transient rectangular pulse technique, which is used in low-emission electron generator, time-stable source for CO_2 laser amplifier and γ- Multi-pulse high-energy lasers for collisions and multi-pack electron generators.
