Abstract

High brilliance performance of chemical oxygen iodine lasers (COIL) requires resonator concepts that enable efficient power extraction from a low gain medium while the beam quality is close to the diffraction limit. Different resonator concepts are pre-evaluated by numerical methods and the promising candidates are adapted to a 10 kW-class COIL system. Theoretical predictions and experimental results are found to be in excellent agreement. The beam quality of different resonator architectures is evaluated by standards reported in literature. A further criterion for resonator assessment is introduced.
