本文报道了在SUNSHINE实验装置上从亚皮秒电子聚束产生的高功率相干远红外波荡器辐射的产生和观测。实现了波长在50 ~ 200 μm范围内可调谐的相干波荡器辐射。测量的能量（高达1.7毫焦耳每1 μs的宏脉冲），频谱，和空间分布的辐射。观察到辐射能量作为波荡器长度的函数的表观指数增长。
The generation and observation of high‐power, coherent far‐infrared undulator radiation from sub‐picosecond electron bunches at the SUNSHINE facility is reported. Coherent undulator radiation tunable from 50 to 200 μm wavelength is demonstrated. Measurements of the energy (up to 1.7 mJ per 1 μs macropulse), frequency spectrum, and spatial distribution of the radiation are reported. Apparent exponential growth of the radiated energy as a function of undulator length is observed.
