Mathematical modeling of TE CO\+v\2\-v\ laser with SF\+v\6\-v\ as a saturable absorber

This paper presents a mathematical model describing the dynamic emission of a single-mode TE CO\+v\2\-v\ laser with saturable absorber. A six-temperature model was used to describe the amplifying medium, while a four-coupled energy level was used to describe the selective absorbing medium. The model allows both the investigation of the effects of the intracavity absorber on the mode characteristics of the TE CO\+v\2\-v\ laser and also the study of the effect 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. Also, numerical solutions of a nonlinear rate equation system are quantitatively discussed.
