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 I_sat of 0.8 MW cm^-3 were calculated for a specific power-density of 320 kW cm^-3.
