Generating Multiple Superradiance Pulses in a Slippage- Dominant Free-electron Laser Amplifier
نویسندگان
چکیده
We report the first numerical demonstration of the generation of multiple superradiance pulses in a slippage-dominant freeelectron laser amplifier. In this simulation, the 1 and 2 multiple radiation-pulses are created from the deformation of the longitudinal phase space. Our simulation confirmed controllability over the temporal profile of these pulses, and paves the way for applying this technique, such as generating multiple pulses for slippage-dominant laser-seeded FELs.

First Demonstration of a Slippage-dominant Superradiant Free-electron Laser Amplifier
We report the first experimental demonstration of a slippagedominant superradiant free-electron laser (FEL) using an ultrafast seed-laser pulse. We measured the evolution of the longitudinal phase space in the slippage-dominant superradiant regime. With a roughly 1% variation in the electron beam energy, we observed a seed-like fully longitudinal coherence, and a 2% wavelength shift from the se...
متن کاملGeneration of ultrashort radiation pulses by injection locking a regenerative free-electron-laser amplifier
We demonstrate how a steady-state train of ultrashort radiation pulses can be produced utilizing a new free-electron laser ~FEL! configuration, the injection-locked regenerative klystron amplifier ~IRKA!. This configuration consists of two elements: ~1! a prebuncher, which microbunches the electron beams at the desired output wavelength, and ~2! a multipass FEL operated at a very small cavity d...
متن کاملExperimental Investigation of Superradiance in a Tapered Free-Electron Laser Amplifier
We report experimental studies of the effect of undulator tapering on superradiance in a single-pass highgain free-electron laser (FEL) amplifier. The experiments were performed at the Source Development Laboratory (SDL) of National Synchrotron Light Source (NSLS). Efficiency was nearly tripled with tapering. Both the temporal and spectral properties of the superradiant FEL along the uniform an...

We present the results of numerical calculations of the effects of noise, slippage and superradiance in the UCLA infrared (IR) free electron laser (FEL). The experiment, which uses a high brightness electron beam produced by a photocathode RF gun and a 1.5 cm period planar undulator, will compare the FELevolution starting from noise to that starting from an input signal . Numerical studies indi...
متن کاملHigh-order-harmonic generation and superradiance in a seeded free-electron laser.
Higher order harmonic generation in a free-electron laser amplifier operating in the superradiant regime [R. H. Dicke, Phys. Rev. 93, 99 (1954).] has been observed. Superradiance has been induced by seeding a single-pass amplifier with the second harmonic of a Ti:sapphire laser, generated in a β-Barium borate crystal, at seed intensities comparable to the free-electron laser saturation intensit...
