摘　　要：钛宝石飞秒激光放大系统具有重复频率低、脉冲波形复杂等特点,为准确测量其峰值功率,提出对单次脉冲波形和脉冲宽度测量的需求。介绍了单脉冲飞秒激光时域波形和脉冲宽度的测量原理和测量方法,设计了基于频率分辨光学开关法的单脉冲飞秒激光时域参数测量装置。讨论了单脉冲飞秒激光时域参数测量校准面临的问题及解决方法。The Ti sapphire femtosecond laser amplification system has the characteristics of low repetition frequency and complex pulse waveform. In order to accurately measure the peak power of the femtosecond laser amplification system, the measurement demand of single pulse waveform and pulse width was proposed.The measurement principle and method of single pulse femtosecond laser time domain waveform and pulse width were introduced, the time domain parameters measuring device of single pulse femtosecond laser based on frequency-resolved optical gating method was designed, and the technical problems and solutions in the calibration of time domain parameters measurement of single pulse femtosecond laser were discussed.
