Simple model of gain saturation in free-electron lasers
Physical Review A, 1991In this paper we analyze the dynamics of a free-electron laser in the strong-signal regime, drawing a parallel with that of a conventional laser. A simple model of gain saturation is developed and a scaling relation of the gain versus the intracavity laser intensity is derived.

The Free Electron Laser: A Single Particle Classical Model
Lettere al Nuovo Cimento, 1978Stimulated processes are the basic phenomena in laser devices, operating either as amplifiers or as optical oscillators. Although the laser operation is best described in the framework of a semiclassical theory, in which the electromagnetic field is not treated quantum mechanically, the basic processes are better understood if we quantize the field ...

Free‐electron model for the inelastic collision of fast electrons with benzene
International Journal of Quantum Chemistry, 1967AbstractUsing a free‐electron wave function the cross section for the excitation of the first excited state and that for the ionization of benzene in the inelastic collision with fast electrons have been estimated. In the ionization process the cross section has been found to be maximum when the secondary electron moves away with a kinetic energy of ...

Note on the Applicability of the Free-Electron Network Model to Metals
Proceedings of the Physical Society. Section A, 1954The free-electron model of a conjugated molecule is extended to apply to a metal. When each conduction electron is allowed to move freely along the set of one-dimensional lines (i.e. bonds) joining adjacent atoms, a band-structure appears. This is shown to be almost identical with the shape predicted by the conventional tight-binding approximation. The

The wiggler-free free-electron laser: A single-particle model
Physics of Fluids B: Plasma Physics, 1992A general single-particle formalism is developed that is applicable for describing thermal and nonlinear effects both in the wiggler-free free-electron laser (WFFEL) and in the cyclotron autoresonance maser (CARM). The general formalism is used in the present paper for a linear analysis. The WFFEL interaction is shown to result from the coupling of the
