| abstract: | The authors study the behavior of a free electron laser in the high gain regime, and the conditions for the emergence of a collective instability in the electron beam-undulator-field system. The authors' equations, in the appropriate limit, yield the traditional small gain formula. In the nonlinear regime, numerical solutions of the coupled equations of motion support the correctness of their proposed empirical estimator for the build-up time of the pulses, and indicate the existence of optimum parameters for the production of high peak-power radiation.

| abstract: | Studies the conditions for collective instability of the electron beam-undulator-radiation field of free electron lasers. The authors derive the characteristic complex frequencies of the FEL. From this result, the small-signal gain formula is obtained. They consider the problem of the initiation of laser action and growth of the radiation field from noise. The nonlinear regime is studied numerically. (14 References). |
