Abstract
We report measurements of very large output intensities corresponding to a gain larger than 10(5) for a single pass free-electron laser oper ating in the self-amplified spontaneous emission (SASE) mode at 12 mu m. We also report the observation and analysis of intensity fluctuatio ns of the SASE radiation intensity in the high-gain regime. The result s are compared with theoretical predictions and simulations.
