โฆ Synopsis
A mathematical model describing the dynamic emission of a single mode TE CO 2 laser with saturable absorber has been adapted. A six-temperature model has been used to describe the amplifying medium, while a four-coupled energy level is used to describe the selective absorbing medium. The suggested mathematical model allows the investigation of the eects of the intracavity absorber on the mode characteristics of the TE CO 2 laser and, moreover, the study of the eect of the laser input parameters on the output laser pulse. The model simulates the passive Q-switch in both low-and high-pressure cases in the absorbing medium.
In addition, numerical solutions of a non-linear rate equation system of the suggested model are quantitatively discussed. The solutions describe the photon number density, the population inversion and the energy transfer processes of amplifying and absorbing media.
