摘要
本文报道了重复频率为 １０Ｈｚ的Ｔｉ： Ａｌ_２Ｏ_３飞秒激光放大器的研究．基于脉冲啁啾放大技术和采用再生／多通放大装置，得到了能量为 ８ｍＪ的放大光脉冲，在该放大系统中，激光脉冲获Ｍ净增益约８×１０_７．
This article described a compact and high efficient solid - state laser system based on Ti: Al_2O_3 capable of producing pulses with energy of 8mJ each at a 10Hi repetition rate. By utilization of chirped pulse amplification technique, u liras bort seed pulses with duration of 100fs and re petit ion rate of 82MHz generated from self-mode-locked Ti: Al_2O_3, laser were stretched to ~ 200ps with a four-pass grating stretcher. After regenerative amplification, a cavity-dumped pulse with energy greater than 2mJ was obtained. We also designed a double-pass power amplifier. The long pulses from the regenerative amplifiers were further amplified to about 8mJ with each pulse's energy. As a result, the total net gain of this system was achived 8 X 10_7
