Abstract

The discharge conditions of the multi-atmospheric e-beam sustained Ar-Xe laser are investigated. It is observed that the quasi-stationary period of a laser pulse depends on the e-beam current, the discharge power deposition and the gas density. The laser efficiency can be as high as 8%. The pulse energy with optimum efficiency depends strongly on the gas density. The best results are obtained for 4 bar with an input power of 8 MW/l. The pulse duration with corresponding output energies are 12 microsecond(s) with 10 J/l and 16 microsecond(s) with 16 J/l for e-beam currents of 0.4 and 0.9 A/cm2 respectively. An analysis of the quasi-steady state conditions that include the effects of electron collision mixing and atomic quenching is presented. The effects of output power saturation by the fractional ionization and atomic collisions are in agreement with the observations. The analysis clarifies the optimum performance conditions.
