“…However, the experimental proof of SASE-FEL theory has taken place at much larger wavelengths (e.g. UCLA-LANL experiment in IR [3]). The objective for this device is to scale the experimental confirmation of theory and simulation into the visible and near IR region, as well as measure saturation and other different aspects of FEL performance.…”

The VISA (Visible to Infrared SASE Amplifier) project is designed to be a SASE-FEL driven to saturation in the sub-micron wavelength region. Its goal is to test various aspects of the existing Spontaneous Emission, theory of Self-Amplified as well as numerical codes. Measurements include: angular and spectral distribution of the FEL light at the exit and inside of the undulator; electron beam micro-bunching using CTR; single-shot time resolved measurements of the pulse profile, using auto-correlation technique and FROG algorithm.The diagnostics are designed to provide maximum information on the physics of the SASE-FEL process, to ensure a close comparison of the experimental results with theory and simulations.

“…Recent experimental demonstrations of SASE in the infrared [3], visible [4] and ultraviolet [5] have increased the enthusiasm for the further development of this approach. The theory of high-gain single-pass free-electron lasers has been developing since the late 1970's [6][7][8][9].…”

In the linear regime before saturation, we describe the statistical correlations in the narrow band chaotic output of the SASE FEL. At a fixed position along the undulator axis, we derive joint probability distributions for the intensity in the output pulse to have values 1 I and 2 I at times 1 t and 2 t , and for the spectral intensity to have values ~1I and ~2I at frequencies 1 ω and 2 ω . Probability distributions for the peak values of intensity in the time and frequency domains are also determined.
