Ginzburg-Landau Model and Single-Mode Operation of a Free-Electron Laser Oscillator
نویسندگان
چکیده
It is shown that the radiation field in a long-pulse, low-gain free-electron laser oscillator obeys the complex Ginzburg-Landau equation. The question of single-mode operation is investigated by analysis and simulation, and the results are compared with experiments at the University of California at Santa Barbara, as well as the Dutch fusion free-electron-maser experiment. It is shown that the intervention of a frequency-dependent reflection coefficient can facilitate the realization of single-mode operation. [S0031-9007(99)08757-8]

Ginzburg}Landau model for a long-pulse low-gain free-electron laser oscillator
The Ginzburg}Landau model for the radiation "eld of a free-electron laser (FEL) was originally derived for a high-gain ampli"er (S.Y. Cai and A. Bhattacharjee, Phys. Rev. A 43 (1991) 6934). With a view to making precise comparisons with experimental data from the long-pulse FEL oscillator at the University of California at Santa Barbara (UCSB) (L.R. Elias, G. Ramian, J. Hu, A.

متن کاملGinzburg-Landau model for mode competition and single-mode operation of a free-electron laser
Mode competition of a free-electron laser is modeled by the Ginzburg-Landau equation. The stability of a single-mode solution is analyzed, and connections are established with known instabilities of the GinzburgLandau equation. It is found that the principal mode with the largest gain is always stable and hence there is no Benjamin-Feir instability. However, the Eckhaus ~or phase! instability g...
متن کاملGinzburg—Landau model for a free-electron laser: from single mode to spikes
Single-mode operation of a free-electron laser is modeled by the Ginzburg—Landau equation. The linear stability of a single-mode solution is analyzed, and connections are established with known instabilities of the Ginzburg—Landau equation. It is found that there is no Benjamin—Feir instability and hence, the principal mode with the largest gain is always stable. However, the Eckhaus (or the ph...
متن کاملNumerical study on self-similar pulses in mode-locking fiber laser by coupled Ginzburg-Landau equation model.
A theoretical model is established to study the self-similar pulses in nonlinear polarization evolution (NPE) mode-locked fiber lasers. The propagation of pulse in single mode fibers and gain fibers are described by coupled Ginzburg- Landau equation (GLE). Two wave plates and a polarizer are considered to realize the NPE mechanism in simulation. This model describes the laser completely and pro...
متن کاملExact solutions of the 2D Ginzburg-Landau equation by the first integral method
The first integral method is an efficient method for obtaining exact solutions of some nonlinear partial differential equations. This method can be applied to non integrable equations as well as to integrable ones. In this paper, the first integral method is used to construct exact solutions of the 2D Ginzburg-Landau equation.
