Abstract

The expression for the gain of an free electron laser (FEL), in which a high current electron beam interacts with laser beat waves (LBW), is obtained. In case of a Gaussian distribution the gain has a maximum near the relativistic plasma frequency of the beam. For frequencies much higher than the plasma frequency, the gain decreases exponentially. In the case of a uniform distribution the gain decreases according to a power-like law, which produces higher values for the same frequencies. It is proposed to use asymmetrically distributed electron beams interacting with LBW to produce intense radiation in the submillimeter region.
