A synchrotron type of radiation spectrum is predicted for interaction
of relativistic electrons with intense laser beams when the field stre
ngth parameter is large; nu(0) > 1. Analytical formulas describing non
-linear effects of higher harmonics generation for the case of linear
polarized laser beams have been obtained. It is shown that in the gene
ral ease the shape of the radiation spectrum is defined by two invaria
nts - nu(0) and a depending on electron energy. (C) 1998 Elsevier Scie
