Paper Abstract

An output beam with a nearly ideal focal spot can be obtained by combining an unstable ring resonator with 90 deg beam rotation with a lasing medium which has gain that would be too low for the effective use of a more conventional unstable resonator. As an example, results are presented of a simulation of an oxygen-iodine transfer laser with moderate gain. The simulation included a fairly detailed representation of the laser kinetics, including the effect of transverse gas flow. Results of the simulation include laser mode profiles and far-field patterns.
