Abstract
The dynamics of the parametric excitation of an electromagnetic field in a cavity that is composed of two plane mirrors has been analyzed. One of the mirrors is immobile and has a finite reflectance spectral band, while the other mirror is oscillating with a wider spectral band. The field energy in the cavity may increase due to a transfer from the kinetic energy of the mirrors. Estimates and calculation results for a Lorentz profile of the spectral band of the reflectance show that, under conditions of a parametric resonance, the initial exponential increase in the field energy in the cavity is stopped and the stable pulse-periodic mode is formed.
