title: Experimental investigation of an unstable ring resonator with 90-deg beam rotation for a chemical oxygen iodine laser.
abstract: We report the experimental results of an unstable ring resonator with 90-deg beam rotation for a kilowatt class chemical oxygen iodine laser (COIL). The distributions of near-field phase and far-field intensity were measured. A beam quality of 1.6 was achieved when the COIL average output power was approximately 5 kW.
