Free electron lasers with electron storage rings

From Storage Rings to Free Electron Lasers for Hard X-Rays

The intensity of X-ray sources has increased at a rapid rate since the late 1960s by 10 orders of magnitude and more through the use of synchrotron radiation produced by bending magnets, wigglers and undulators. Three generations of radiation sources have been identified depending on amplitude and quality of the radiation provided. While user facilities of the third generation were being constr...

Lasers , Free - Electron

Free-electron lasers are radiation sources, based on the coherent emission of synchrotron radiation of relativistic electrons within an undulator or wiggler. The resonant radiation wavelength depends on the electron beam energy and can be tuned over the entire spectrum from micrometer to X-ray radiation. The emission level of free-electron lasers is several orders of magnitude larger than the e...

Macro-temporal structure of storage ring free electron lasers

2014 I derive simple dimensionless equations governing the storage ring free electron laser behaviour around a steady state of constant power and electron energy spread It is found that the laser tends to have a macrotemporal pulsed structure (in the range of milliseconds). By periodically modulating the laser gain, one can achieve a peak power much higher than the average power which stays lim...
