本文成功地证明了皮秒脉冲自由电子激光（FEL）辐射用于连续波太赫兹范围的电子自旋共振（ESR）光谱。两个基于直线加速器的FELs（覆盖波长范围为4-250微米）与脉冲磁场高达70 T的组合允许在1.2-75太赫兹的频率范围内进行多频ESR光谱，光谱分辨率优于1%。通过对2,2-二苯基-1-吡啶酰肼和低维有机材料（C6H9N2）CuCl3的ESR光谱分析，说明了该光谱仪的性能。
The successful use of picosecond-pulse free-electron-laser (FEL) radiation for the continuous-wave terahertz-range electron spin resonance (ESR) spectroscopy has been demonstrated. The combination of two linac-based FELs (covering the wavelength range of 4-250 microm) with pulsed magnetic fields up to 70 T allows for multifrequency ESR spectroscopy in a frequency range of 1.2-75 THz with a spectral resolution better than 1%. The performance of the spectrometer is illustrated with ESR spectra obtained in the 2,2-diphenyl-1-picrylhydrazyl and the low-dimensional organic material (C6H9N2)CuCl3.
