Paper Abstract

The concept of coupled resonator beam combining is introduced via laboratory experiments and a model based on the coupled laser theory of Spencer and Lamb. In the laboratory experiments a pair of half-symmetric CO2 unstable resonators were coupled to provide a pair of mutually coherent output beams. The coupling was introduced in the symmetry plane of the resonators with either beamsplitters or hole couplers. The beamsplitter coupling configurations were used to experimentally verify the stability region of the coupled lasers, predicted by the Spencer-Lamb model, as a function of the coupling coefficient. The corresponding behavior was then investigated for the hole coupled lasers with hole size and position as parameters.
