The high pressure (> 0.5 atm) atomic Xe laser oscillates on at least 5 infrared transitions (1.73 {mu}m - 3.51 {mu}m), and operates at high intrinsic efficiencies (< 5%) using a variety of excitation sources. Recently pulsed electric discharge and microwave excitation has been experimentally investigated. The authors have developed computer models of those lasers to study scaling of the laser at high pump rates and energy deposition. A new modeling technique was developed which extends the use of the local field approximation for high pressure discharges to conditions where zero-crossings in the electric field occur. The authors find that microwave excitation is nearly equivalent to particle beam excitation when compared on the basis of power deposition, and exhibits similar high gas temperature effects. Pumping the Xe laser using a TEA discharge optimizes at lower Xe concentrations than using microwave or particle beam excitation.
