High Power Short Wavelength Laser Development

Abstract

Results of a comprehensive experimental and theoretical investigation of a large volume, electron beam and discharge excited KrF laser are reported. For pulse lengths approx. 1 microsec, maximum specific energy extraction was 22 J/liter at 10% efficiency and maximum total energy was 90J for a 10 liter gain volume. Discharge enhancement of output energy was limited by discharge instability as a result of beam deposition nonuniformity. Excellent agreement in terms of absolute values and waveforms was obtained with an extensive computer code.
