Abstract
A number of unique properties of the electric-discharge XeCl laser, like possibility to generate laser pulses with duration from single nanosecond to hundreds ns, continues to attract a research interest to that laser system. It follows from an analysis of the laser characteristics obtained by different groups throughout the world [1], conditions of the laser generation to a great extent influence the output laser characteristics. The highest laser efficiency of 4-5% with the specific radiation energy 2-3 J/l is achieved at the pulse durations of 200-100 ns and pumping power of ~0.5 MW/cm3. Laser regimes characterized by high radiation energy of 7-10 J/l, but lower efficiency of 1-3% has been realized at a pulse duration of ~50 ns and pumping power of 2-10 MW/cm3. An increase of the radiation power becomes possible in regimes with a short pumping pulse of 30-20 ns, but at the cost of the laser efficiency, which decreases to 2-3%. The aim of the present work was a search of some general (independent on the pumping regimes) relationships, which could be used as a guideline for the choice of the initial conditions for creation of lasers with desirable parameters. Computer modeling was used as a research method, since it allows to a full extent explore the relation between the output characteristics of a laser and the initial conditions.
