Abstract
We report measurements of very large output intensities corresponding to a gain larger than for a single pass free-electron laser operating in the self-amplified spontaneous emission (SASE) mode at . We also report the 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.
