Abstract
An output beam combining apparatus for recombining diverging output beams from a ring laser. One preferred embodiment of the present invention includes a first planar mirror mounted to an exterior surface of a ring laser output mirror and having a reflective coating oriented generally perpendicular to the output mirror along with a second planar mirror disposed adjacent to the first mirror and having a reflective coating oriented perpendicular to the reflective plane of the first mirror. In use a first output beam from the ring laser is reflected back to the rear surface of the ring laser output mirror along a path parallel to but displaced from its initial path. This return beam is then reflected off of the rear surface of the output mirror along a path that is collinear with a second output beam from the ring laser so as to form a combined beam that is directed to a suitable detector.
