Some Aspects of Chaotic Lasing in Volume Free Electron Lasers.
S. N. Sytova

Chaotic dynamics in Volume Free Electron Lasers (VFEL) is excited by significant perturbation in movement of electrons through resonator and by deformation of bunches leading to generation of higher harmonics in the system and vice versa. Analysis of phase electron dynamics are presented to explain origin of chaos in VFEL. Investigations presented are attempts to display origin of steady-state stationary and oscillatory VFEL regimes and demonstrate structure of electron bunches originating when electron beam passing through photonic crystal in VFEL.
Key words: Volume Free Electron Laser, mathematical modelling, chaos
