Influence of translational and hyperfine relaxation on energy characteristics of oxygen-iodine laser
Abstract
The influence of translational and hyperfine relaxation on the energy characteristics of chemical oxygen iodine lasers is investigated. In the model, a homogeneous stream of oxygen, atomic iodine, argon and extinguishing impurities moves in a uniform velocity in a flat Fabry-Perot resonator. It is found that relatively low quenching rates at pressures of 1-5 mm Hg can cause a two fold drop in the laser power. The results obtained are for single mode lasing realized in resonators with short optical length. The nonuniform broadening and finite relaxation times noted must be taken into account in the practical development of chemical oxygen lasers and in the numerical modeling of lasing kinetics.
