摘要
介绍了一种高重复频率掺钛蓝宝石飞秒激光多通高效率放大系统.在抽运功率为23W,入射功率为660mW时,获得7.2W的放大输出,放大效率达30%.经压缩器压缩后,获得单脉冲能量4.5mJ,脉冲宽度为38fs,重复频率为1kHz,峰值功率大于0.1TW的超短超强激光脉冲.
A Ti ： sapphire multipass amplifier with high efficiency at the repitation of 1 kHz is described. The incident 0.66 W pulses are amplified to 7.2 W when the pump power is 23 W. The energy extraction efficiency is about 30%. After compressed in the compressor, we obtained 4.SmJ, 38fs pulses with peak power greater than 0.1 TW.
