title: Annular converging wave resonator: new insights.
abstract: A simple theory describing the annular converging wave resonator has been developed. The theory explains results obtained in two recent experiments. Configurations of the converging wave resonator that could be used to extract power from a large-volume annular gain region in a single mode with nonzero azimuthal order are also discussed.
