Vi. Alekseev et al., ON OBTAINING MONOCHROMATIC RADIATION OF F REE-ELECTRONS LASER BY MEANS OF COUPLED CAVITIES (MODE SELECTION METHOD), Kvantovaa elektronika, 20(6), 1993, pp. 601-607
The problem of obtaining highly monochromatic radiation of the paramet
ric free electrons lasers by means of a system of coupled cavities has
been investigated. The optimum design of the system has been searched
for. It is shown that the radiation intensity can be kept practically
constant, as monochromaticity of the radiation is improved.
