Abstract
A negative branch hybrid resonator was coupled to the 10kW-class Chemical Oxygen-Iodine Laser (COIL) device of DLR. Resonator set-up and alignment turned out to be straight forward. Experimentally measured margins for mirror misalignment were found in close agreement to numerical calculations. The extracted power came up to 70% of the power coupled out of a stable resonator device, while the divergence of the emitted light obtained in unstable direction was lower than 2 times diffraction limited.
