Abstract

Through combined three-dimensional electromagnetic and particle tracking simulations we demonstrate a THz driven electron streak camera featuring a temporal resolution on the order of a femtosecond. The ultrafast streaking field is generated in a resonant THz sub-wavelength antenna which is illuminated by an intense single-cycle THz pulse. Since electron bunches and THz pulses are generated with parts of the same laser system, synchronization between the two is inherently guaranteed.

摘要

通过结合三维电磁和粒子跟踪模拟，我们展示了一种太赫兹驱动的电子条纹相机，其时间分辨率约为飞秒量级。超快条纹场在一个共振太赫兹亚波长天线中产生，该天线由一个强单周期太赫兹脉冲照射。由于电子束团和太赫兹脉冲由同一激光系统的不同部分产生，两者之间的同步从本质上得到了保证。
