Free-electron lasers are tunable, potentially powerful sources of coherent radiation over a broad range of wavelengths from the far-infrared to the far-ultraviolet regions of the spectrum. These unique capabilities make them suitable for a broad variety of applications from medicine to strategic defense. 

Free‐electron lasers

A new method of using an additional laser for electron-beam conditioning in free-electron lasers and synchrotrons is proposed and the axial energy spread of electrons due to their betatron motion in undulators can be dramatically reduced by interacting with a quasi-TEM[sub 10] mode Gaussian optical beam.

A proposal for an X-ray free-electron laser oscillator with an energy-recovery linac.

We show that a free-electron laser oscillator generating x rays with wavelengths of about 1 A is feasible using ultralow emittance electron beams of a multi-GeV energy-recovery linac, combined with a

Efficiency optimization for free-electron laser oscillators

Using a normalized set of nonlinear equations, which describe a free‐electron laser (FEL) oscillator, the efficiency of energy extraction from the electron beam to the radiation can be optimized. The

Observation of single-mode operation in a free-electron laser.

Time-structure and frequency-spectrum measurements of the UC Santa Barbara free-electron-laser oscillator show that for periods shorter than 5 microsec, the laser-frequency changes in unexpected quantized steps, which may be explained in terms of a homogeneously broadened gain profile coupled to a small monotonic drift in electron-beam energy.
