在汉堡的自由电子激光器Freie-Elektronen-Laser（FLASH）上，利用500 MeV电子束团的相干跃迁辐射产生了能量高达100 μ J的太赫兹（THz）脉冲，相应的电场高达1 MV/cm。脉冲的特征在于在时域的电光采样的同步飞秒激光抖动小于100 fs。高太赫兹场强度和与光学激光的同步质量将使得能够观察到非线性太赫兹现象。(C)2011年美国光学学会
Terahertz (THz) pulses with energies up to 100 mu J and corresponding electric fields up to 1MV/cm were generated by coherent transition radiation from 500 MeV electron bunches at the free-electron laser Freie-Elektronen-Laser in Hamburg (FLASH). The pulses were characterized in the time domain by electro-optical sampling by a synchronized femtosecond laser with jitter of less than 100 fs. High THz field strengths and quality of synchronization with an optical laser will enable observation of nonlinear THz phenomena. (C) 2011 Optical Society of America
