在未加任何色散补偿的情况下,用相关方法直接测量得到了脉冲宽度为39fs的单次放大激光脉冲。为实时测量低重复频率的超短强激光脉冲提供了可靠的手段。
Without any dispersion compensation, a single amplified laser pulse with a pulse width of 39 fs was directly measured using the correlation method. It provides a reliable method for real-time measurement of ultrashort laser pulses with low repetition rate.
