<p>A gas ion laser is described having a resonator structure which not only maintains the optical reflectors of the laser at the respective ends of the optical cavity in a selected relationship, it also maintains an optical element 48, 49 external of such laser in a predetermined relationship to the output beam of the laser. The resonator stucture includes a plurality of rods 17,18,19 which extend between mounts 21, 22 for the optical reflectors 14 parallel to and adjacent the laser optical cavity. Such rods project beyond the optical cavity mount 22 selected to hold a partially transmissive optical reflector to define the laser output beam, and terminate in a third mount 43 which maintains a desired optical element 48, 49 in a predetermined relationship relative to the laser output beam.</p> |
