Abstract

A rectangular negative branch off-axis hybrid resonator was coupled to a 10-kW class Chemical Oxygen-Iodine Laser (COIL). Resonator setup and alignment turned out to be straight forward. The extracted power was 6.6 kW and reached about 70% of the power for an optimized stable resonator. The divergence of the emitted laser beam in the unstable direction was lower than 2 times diffraction limited. Experimentally measured margins for mirror misalignment were found in close agreement with numerical calculations.
