We report on an experimental measurement of the pulse front tilt (PFT) of spatiotemporally focused femtosecond laser pulses in the focal plane in both air and bulk transparent materials, which is achieved by examination of the interference pattern between the spatiotemporally focused pulse and a conventional focused reference pulse as a function of time delay between the two pulses. Our simulation results agree well with the experimental observations.
我们报告了在空气和块状透明材料的焦平面中对时空聚焦飞秒激光脉冲的脉冲前沿倾斜（PFT）进行的实验测量，这是通过检查时空聚焦脉冲与传统聚焦参考脉冲之间的干涉图案作为两个脉冲之间时间延迟的函数来实现的。我们的模拟结果与实验观测结果吻合良好。
