  • 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23 W，入射功率为660 mW时，获得7.2 W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4.5 mJ,脉冲宽度为 38 fs，重复频率为1 kHz，峰值功率大于0.1 TW的超短超强激光脉冲.

     

    Abstract

    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 4.5mJ, 38fs pulses with peak power greater than 0.1 TW.
