提出了一种基于光学偏振技术的飞秒激光脉冲在透明介质中传播的多帧观测方法。在探测光中引入一个梯队，并将其在时间和空间上划分为多个脉冲，从而允许对在材料中传播的强激光脉冲进行多帧检测。利用这种方法，我们实现了单飞秒激光脉冲在CS2中传播的多帧观测。这种成像方法已被证明具有飞秒时间分辨率和~太赫兹的帧速率。
We developed a multiframe observation method of femtosecond laser pulse propagating in transparent medium based on optical polarigraphy technique. An echelon was introduced into the probe light and divided it into multipulses both in time and space, allowing a multiframe detection of the intense laser pulse propagating in materials. Using this method, we realized a multiframe observation of a single femtosecond laser pulse propagating in CS2 with ultrafast self-modulation such as filamentation. This imaging method has been demonstrated to be of a femtosecond time resolution and a frame rate of ~ THz.
