Characterization of a High Uniformity, X-ray Preionized XeCl Laser

摘要

The construction and operating characteristics of an X-ray preionized discharge XeCl laser are described. A specific laser output energy of 3.3 J/liter, with a pulse-width of 150 ns and a spatial beam uniformity better than 90% in a 3.5x3.5 square centimeter cross section, was achieved. Intrinsic efficiency up to 3.6% was obtained without the use of an external prepulse circuit. A fast, high voltage prepulse to intensify the preionization was succesfully tried out, obtaining a better energy coupling to the gas and more reliable conditions at lower working voltage.
