Abstract
We report measurements of large gain for a single pass free-electron laser operating in self-amplified spontaneous emission (SASE) at 16 μm starting from noise. We also report the first observation and analysis of intensity fluctuations of the SASE radiation intensity in the high gain regime. The results are compared with theoretical predictions and simulations.Keywords
