Abstract

A Cerenkov gas laser would consist of a suitable gas at near atmospheric pressure, a highly relativistic electron beam, and an optical cavity. The electron beam emits spontaneous Cerenkov radiation which is reflected on the beam at the Cerenkov angle by the cavity. This, in turn, stimulates further emission. In an idealized situation the predicted gain of such a system, when operated in the visible region of the spectrum, could be quite high (many percent/pass). Results of an idealized calculation and departures therefrom caused by finite beam emittance and energy spread, velocity space diffusion of the beam in the resonator, and constraints imposed by beam and cavity characteristics will be discussed.
