Abstract
A modification to the reflective surfaces in unstable resonator assemblies to improve the operating characteristics of such devices and enhance the quality in the far field of the output beam from such resonators is disclosed. Some modifications include the elimination of abrupt discontinuities in the reflective surfaces and the forming of an auxiliary unstable resonator along the centerline axis of the primary resonator and result in increased symmetry in the operating characteristics of the system in the gain region and improved intensity profile in the far field for the output beam. The concept is applicable to axial as well as radial flow resonators having either circular or cylindrical optics.
