Paper Abstract

For a 10kW-class Chemical Oxygen Iodine Laser (COIL), negative and positive branch hybrid resonators are investigated in theory and experiment. Calculations from Fresnel-Kirchhoff theory predict a nearly diffraction limited beam quality in the unstable direction. Theory is verified by measurements with a 2D-camera system in the far field.
