Kinetics of the active medium of a multiwave IR xenon laser in hard-ioniser-pumped mixtures with He and Ar. II. Nuclear pumping

The results of calculations based on a new detailed nonsteady-state multiwa ve kinetic model of a laser based on xenon atom transitions with lambda = 1 .73, 2.03, 2.65, 2.63, 3.37, and 3.51 mu m in an He-Ar-Xe mixture were comp ared with the results of experimental studies of a nuclear-pumped xenon las er carried out making use of several experimental setups. A satisfactory ag reement between the calculations and experiments was achieved. The causes o f the impairment of the nuclear-pumped xenon laser characteristics with inc rease in the temperature of the medium were discovered. It was found that n uclear pumping of a Ar-Xe mixture can result in attaining a lasing efficien cy up to 3.5%. A laser nuclear-pumped by the VIR-2M reactor was fully optim ised.
