太赫兹自由电子激光与飞秒激光高精确度同步验证
Technical verification of high precision synchronization between THz-FEL and fs-laser
摘要
Abstract
To conduct ultrafast application experiments such as terahertz-laser pump-probe experiments on the Terahertz Free Electron Laser Facility(THz-FEL),it is necessary to achieve high-precision synchronization at the femtosecond level between terahertz pulses and laser pulses.A technical method is proposed based on photoelectric detection and fast feedback from piezoelectric ceramics.Terahertz pulses are generated using the organic crystal N-Benzyl-2-methyl-4-nitroaniline(BNA),and the random jitter of the free electron laser pulses is simulated using an electrically controlled displacement stage.The piezoelectric fast feedback compensation system rapidly adjusts the optical path of the laser to reduce the jitter range,achieving high-precision real-time following of the terahertz pulses by the laser pulses.关键词
