Abstract Results are reported from a theoretical and experimental investigation aimed at obtaining lasing on transitions of an Ar2 excimer laser pumped by a pulsed electric discharge. It is shown that by using a recently developed plasma-cathode discharge, quasi-cw excitation of the laser active medium can be achieved with a gain of around 0.1 cm−1. The results of preliminary experiments performed using a model system indicate an effect wherein the duration of the spontaneous emission at the gl=126 nm transition of the Ar2 dimer decreases monotonically as its peak intensity increases. This behavior, which is observed with increasing pump intensity, is evidence of a stimulated emission effect in the system. However, the measurements indicate that no amplification takes place in the active medium because of accidental impurities in the working gas.
