Electron Beam Pumped XeF (C yields A) Laser Scaling

Abstract

Efficient operation of the electron beam pumped XeF (C to A) laser under conditions which are scalable to large devices has been demonstrated. A five-component laser gas mixture at a pressure of 2.6 ATM was pumped at a rate of 290 kW/cm3 with a 600-ns electron beam pulse. The laser gas mixture and output coupler reflectivity were carefully optimized under free-running conditions, and radiation was then injected into the stable cavity from an external flashlamp-pumped dye laser to reduce the flux buildup time to saturation levels. An intrinsic efficiency of 1.8% and a specific output energy of 3 J/l were demonstrated, and a total energy of 4 J was extracted from the e- beam excited medium.
