Influence of SF6 on the energy characteristics of an H2–F2 chemical laser
V. I. Igoshin, S. Yu. Pichugin
Abstract:
A model of a hydrogen fluoride laser taking into account the finite rate of rotational relaxation is used to study the influence of the addition of SF6 to the mixture on the energy characteristics of a pulsed H2–F2 chemical laser. A comparison between the results of the calculations and the experimental data suggests that an increase in the laser energy with increasing SF6 concentration in the active mixture is largely due to a rise in the rate of rotational relaxation of the HF molecules. It is shown that a drop in the specific laser output energy at very high SF6 concentrations is not only due to an increase in the rate of vibrational–rotational relaxation, but also to the influence of the resonator threshold on the laser energy characteristics as a result of the appreciable broadening of the HF vibrational–rotational lines.
