Abstract

In a free electron laser, a beam of relativistic electrons passes through a static periodic magnetic field to amplify a superimposed coherent optical wave (Figure 1). Here, the lasing process has been reduced to its most fundamental form and is manifestly classical in nature. This point is at the root of many of the free electron lasers potential advantages over conventional atomic lasers; many properties of atomic lasers such as efficiency, are limited by quantum mechanics. This new laser is free from the bonds constraining atomic lasers to a particular wavelength and therefore is continuously tunable. The optical cavity contains only light, radiating electrons and the magnetic field so that intense optical fields may propagate without the degrading non-linear effects (self-focussing, etc.) of denser media. The advanced technology of high-energy electron accelerators and storage rings promises efficient recirculation of the beam energy.
