Abstract

The Visible to Infrared SASE Amplifier (VISA) experiment presented an extensive study of the dynamics of a high gain self-amplified spontaneous emission free-electron laser (SASE FEL) driven by a high brightness, longitudinally compressed electron beam in a strong focusing, compact undulator. A gain of 2x108 and saturation were obtained, and the statistical properties of the SASE signal at saturation were measured. SASE evolution as well as spectral and statistical properties of the radiation were measured and found to be in good agreement with the 3D FEL theory.
