Abstract: The laser resonator system includes a first reflector; a second reflector; at least a first gain medium; a second gain medium; and, an Offner relay system. The first gain medium and the second gain medium are operatively positioned relative to the first and the second reflectors. The first and second gain media generate a laser beam. The Offner relay system is operatively positioned between the first and the second gain media for relaying the laser beam between the first and the second gain media. The laser resonator system uses the Offner relay system for optimal transmission of the laser beam between the two gain media.

Abstract: A system for detecting deviations from an optical axis of one or more individual component beams associated with plural laser beams. The system includes a first mechanism that selectively isolates individual component beams from plural laser beams and provides the individual component beams as output in response thereto. A second mechanism detects deviations from a desired optical axis of the individual component beams output from the first mechanism. In the specific embodiment, the system further includes a mechanism that automatically corrects the detected deviations of each component beam of the plural beams. A beam pick-off device, such as a pick-off collimating lens or beam splitter, redirects a sample of the plural beams, which represents separated plural beams to a color wheel. The individual component beams include red, green, and blue laser beams.
