Endeavour, 1984
The generation of coherent synchrotron radiation using beams of relativistic electrons passed through magnetic undulators opens up tremendous scope for photochemistry in general and isotopic separation by laser in particular. Applications for plasma heating in Tokamak-type installations to trigger off the controlled nuclear fusion process are also ...

Uspekhi Fizicheskih Nauk, 1979
Recent studies devoted to the problem of constructing a free-electron laser are reviewed. Possible approaches to description of the physical processes on which free-electron lasers are based are discussed briefly, and means of increasing the efficiency of laser arrangements are considered.

Science, 1978
In a free electron laser, optical radiation is made to interact with a beam of relativistic free electrons in the presence of a strong spatially periodic transverse magnetic field. This device is interesting because the operating wavelength can be set at will by variation of the electron energy and the device is potentially capable of operating at high

The Physics of Fluids, 1977
The possibility of a new type of laser has been investigated by computer simulation using a fully relativistic electromagnetic particle code which has one spatial and three velocity dimensions. By passing a relativistic electron beam over a rippled static magnetic field, high frequency electromagnetic radiation is generated. If the ripple wavelength is

Data storage applications of magnetism utilize dynamic processes on sub-nanosecond time scales and on length scales of less than 100 nm. Magnetization dynamics on the sub-picosecond time scale has been observed and may lead the way to novel devices.

Bell System Technical Journal, 1978
An introductory guide to the basic mechanisms of the free electron laser is presented. The laser gain originates from the stimulated Raman or Compton backscattering of a pump electromagnetic field by a relativistic electron beam. The condition of optimization of the gain, the maximum operation frequency, and the optimum output power are obtained in ...

Abstract Free-electron lasers (FELs) are classical lasers that can provide widely tunable, highly intense, ultrashort laser pulses in any part of the spectrum. We present here the basic principles and advantages of FELs, discuss the emergence of self-amplified spontaneous emission FELs as leading candidates for X-ray lasers and fourth-generation ...

In our description of undulator radiation, we saw the enormous gains that could be achieved if radiation from separate magnetic poles were added coherently. As a reminder, when N equal sources are added coherently, the produced intensity I varies as N2, compared to intensity gains of only N when the sources are added incoherently.

Free electron lasers are electron beam-based sources of coherent, high-power tunable radiation which can, in principle, be designed to operate at any wavelength ranging from mm waves to X-rays. In recent years, these devices have successfully been operated at THz and hard X-ray wavelengths where conventional sources of radiation are either not ...
