Laser-to-waveguide coupling devices and methods are disclosed employing an aperture, and an imaging lens. The aperture clips the beam edges to flatten the spatial intensity profile, and the lens mirror-images the plane of the aperture onto the waveguide face with appropriate magnification or demagnification...http://www.google.fr/patents/US4842360?utm_source=gb-gplus-shareBrevet US4842360 - High energy laser-to-waveguide coupling devices and methods
