Abstract

The saturation irradiance and line-shape parameters of a high-gain laser transition are determined by analyzing the measured gain of a gas-laser amplifier as a function of incident radiation, based on a quadratic approximation to the saturated gain. Experimental results for a high-gain xenon 3.5 μm (5d33–6p22) laser amplifier are presented.
