2008-12-12 Mathematical Modelling and Analysis, 2008, Vol. 13, № 2, P. 263–273 Keywords: free electron laser, simulation, nonlinear integro-differential system, dynamical system, chaos Nonlinear phenomena originating in volume free electron laser (VFEL)
are investigated by methods of mathematical modelling using computer code VOLC.
It was demonstrated the possibility of excitation of quasiperiodic oscillations not far
from threshold values of electron beam current density and VFEL resonator length.
It was investigated sensibility of numerical solution to initial conditions for different
VFEL regimes of operation. Parametric maps with respect to electron beam current
and detuning from synchronism condition present complicated root to chaos with
windows of periodicity in VFEL. Investigation of chaotic lasing dynamics in VFEL
is important in the light of experimental development of VFEL in Research Institute
