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.
