摘要：

A theory of a relativistic beam amplifier is presented. Owing to backscattering of radiation from a beam of relativistic atoms or ions, frequency up-conversion of the radiation from the infrared to the soft x-ray region is possible, a process that is enhanced if the incident radiation is resonant with an atomic transition. Methods for achieving amplification of the scattered radiation based on Rayleigh and Raman scattering are discussed. Requirements for beam density and field power are estimated. A comparison with requirements for the free electron laser is made. © 1995 The American Physical Society.
