Is the free-electron laser a laser?
Physics Letters A, 1979Abstract The question is discussed in how far a free-electron laser can be called a laser.

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.

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.
