Аннотация на английском языке
Oscillation and amplification regimes of Volume Free Electron Laser (VFEL) operation under condition of multiwave volume distributed feedback (VDFB) are discussed. Electron beam instabilities in VFEL transfer it to regenerative amplification regime (first transition point), steady oscillation regime (second transition point), to nonstationary oscillation regime and through the series of transition points to chaos under increasing current. Nonstationary regime is characterized by changing of oscillation frequency in series of transition points. Some results are obtained analytically. Most part of results is produced by numerical simulation of nonlinear VFEL dynamics. Dependence of transition currents in transition (bifurcation) points on VFEL parameters is demonstrated.
