Abstract
The optical design of a laser resonator smooths out the intensity beam profile of the generated laser beam and prevents the formation of "hot-spots." The active laser resonator containing the active laser medium is optically coupled to a free space passive optical resonator to provide mixing and filtering of the spatial modes.
