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 ...

Abstract Chapter 8 returns to studying synchrotron emission from purpose-built instruments. Free-Electron Lasers (FELs) are especially-designed machines for the production of laser-like light by means of ultra-relativistic electrons in an undulator.

Lasers based on the stimulated emission of radiation by free electrons in a spatially periodic magnetic field offer a unique potential for tunable operation at high power and high efficiency. Substantial advances have been made recently in the theoretical analysis of this class of device and in the operation in our laboratory of a 10 μ free electron ...

In Chap. 1 we have shown that the interaction of electrons with an electromagnetic wave is possible even when the phase velocity of the latter is larger than \( c \), provided that there is a way to conserve simultaneously both energy and momentum. In a free-electron laser (FEL) this is facilitated by the presence of a periodic magnetic field.

We have investigated the possibility of a new type of laser by computer simulation using a 1–2/2 dimensional fully relativistic electromagnetic particle code. By passing a relativistic electron beam over a rippled static magnetic field, high frequency electromagnetic radiation is generated.
