Paper Abstract

The net small-signal gain was measured in a discharge-pumped KrCl laser (222 nm) operated at high gas pressures of around 3.3 bar. The pump power-density was varied between 200-650 kW cm-3. The experiments were carried out on a three-electrode laser system. The net small-signal gain was measured in an oscillator-amplifier configuration and reached up to 1.4 % cm-1. Values for the small-signal gain g0 of 1.50 % cm-1, the nonsaturable absorption &agr; of 0.07 % cm-1 and the saturation intensity Isat of 0.8 MW cm-3 were calculated for a specific power-density of 320 kW cm-3.
