We present the first observation of self-amplified spontaneous emission (SASE) in a free-electron laser (FEL) in the vacuum ultraviolet regime at 109 nm wavelength (11 eV). The observed free-electron laser gain (approximately 3000) and the radiation characteristics, such as dependency on bunch charge, angular distribution, spectral width, and intensity fluctuations, are all consistent with the present models for SASE FELs.
我们首次观测到了波长为109纳米（11电子伏特）的真空紫外波段自由电子激光器（FEL）中的自放大自发辐射（SASE）。观测到的自由电子激光增益（约为3000）以及辐射特性，如对束团电荷量的依赖性、角分布、光谱宽度和强度涨落等，均与目前关于自放大自发辐射自由电子激光器的模型相符。
