The methods of research - the hierarchic approach to the theory of oscillations and waves was used as the basic mathematical apparatus for theoretical research of nonlinear processes in SFELs. The modernization of averaged characteristics method was conducted in the part of the development of asymptotic integration schemes that combine direct and reverse transitions. We have developed quadratic nonlinear theory of plasma-beam superheterodyne free-electron lasers with off-axis electron beam injection.
