RADIOMETRIC CONSIDERATIONS IN CURVED MIRROR GAS LASERS,
Abstract
It is shown that for practical purposes the amount of radiant flux that can be put in a col limated beam is limited by the flux available in the TEMoo mode, and that one cannot increase the radiant flux in a collimated beam by operating the laser in a higher order mode. It would thus appear that, in applications which involve colli mating the laser beam, it is desirable to operate the laser in the TEMoo mode, since the additional radiant flux contained in the higher order modes is not useful. The problem of maximizing the flux in the TEMoo mode is considered. The ef fects of changing the geometry of a curved-mirror laser on the flux available in the TEMoo mode are discussed. It is shown that the maximum amount of flux in the TEMoo mode should result fing mirrors with infinite radius of curvature (i.e. a plane-parallel laser), but that practical considerations favor the use of mirrors with very long (but finite) radius of curvature.
