论文摘要
我们提出了一种用于空间和时间分辨时空振幅的单发测量的技术,以及超耗电激光脉冲的相位。该方法是通过携带时空光学涡流(STOV)的短脉冲的时空成像证明了该方法的瞬时超前光谱干涉法(TG-SSSI)。 TG-SSSI非常适合表征具有与自旋/轨道角动量或极化相关的奇异性的超短激光脉冲。
We present a technique for the single-shot measurement of the space- and time-resolved spatiotemporal amplitude and phase of an ultrashort laser pulse. The method, transient-grating single-shot supercontinuum spectral interferometry (TG- SSSI), is demonstrated by the space-time imaging of short pulses carrying spatiotemporal optical vortices (STOVs). TG-SSSI is well-suited for characterizing ultrashort laser pulses that contain singularities associated with spin/orbital angular momentum or polarization.
