    "abstract": "We present the first observation of Self-Amplified Spontaneous Emission\n(SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109\nnm wavelength (11 eV). The observed free-electron laser gain (approx. 3000) and\nthe radiation characteristics, such as dependency on bunch charge, angular\ndistribution, spectral width and intensity fluctuations all corroborate the\nexisting models for SASE FELs.",
