Nonlinar optical properties of the active medium in intracavity phase conjugation of the radiation of a pulsed electron-beam-controlled discharge CO_2 laser. II. Theoretical analysis

摘要

Numerical simulation is used as the basis of an analysis of nonlinear optical properties of the active medium in intracavity four-wave mixing of the radiation of a pulsed electron-beam-controlled discharge CO_2 laser on saturated-gain and refractive-index diffraction gratings. The reflection coefficient of the phase-conjugated signals is determined for various cavity Q-factors, specific input energies, and pressures of the laser-active mixture. A comparison is made of the theoretical and experimental results.
