<p>An optical apparatus is disclosed suitable for coupling discrete sources of radiation beams onto the input end of an optical fiber or a fiber laser, the optical apparatus comprising a unitary beam deflector having a plurality of deflecting facets where each deflecting facet is oriented so as to deflect an incident beam of radiation into the fiber, an input afocal relay optical system to image a beam of radiation onto a corresponding deflecting facet, and an output afocal relay optical system to image the facet beam images onto the optical fiber or laser fiber end.</p> |
