A scaling-law, function of the longitudinal and the transverse aspect ratios of a laser-produced plasma gain-medium, is derived to predict the saturation gain-length product for short-wavelength lasing. Benchmarking with experimental data from the literature shows how critical is the plasma geometry and, henceforth, the focusing of the pump laser pulse.
