  • Abstract
    We report on theoretical and experimental investigations of the excitation of graded-index fiber modes by a laser beam. The far-field irradiance distribution and the focusing qualities are measured and are related to the measured refractive-index profiles of some commercially available graded-index fibers. If the fundamental mode is the only one excited, fibers with smooth and homogeneous profiles give good output beam qualities for fiber lengths of several tens of meters.
