Discharge nonuniformities influence on the output parameters of a short pulse XeCl laser

摘要

Influence of the discharge burning conditions on output radiation parameters and overall performance of a discharge pumped XeCl laser with pump pulse duration of 20 ns is experimentally investigated. It is shown that a 3.9 J/l·atm maximal specific output laser energy from the active medium is realized in the discharge consisting of the strongly pronounced macro heterogeneities. Laser efficiency of a 2.7 % is reached at discharge current density of a 1.2 1.4 kA/cm~2.
