A novel unstable resonator with a phase-unifying output coupler has been developed. The output coupler structured with a partial-reflection region in its center surrounded by an antireflection region unifies the phases of laser beams passing through these regions. Thus, a near-Gaussian far-field pattern beam has been obtained with a divergence full-angle of 1.08 mrad on the application to a high-power cw CO/sub 2/ laser.
