The subjects of laser initiation and beam quality evolution in short-pulse-duration systems that employ confocal unstable resonators motivated this work. Experimentation and analysis of the performance of a laser-pumped, organic dye laser are presented. Combined results indicate that a saturation flux arises through a coalescence of stabilized, diverging-mode components of the initially emitted fluorescence. The <i>ABCD</i> law method was used to devise calculational techniques that clearly demonstrate the particular mechanisms responsible for rapid mode stabilization, subsequent beam quality development, and laser initiation.
