Abstract
An apparatus for optically pumping an optical fiber from the side comprising a laser for supplying a beam of pump light, and an optical fiber having a longitudinal surface disposed to the beam, a grating formed in the flat surface for diffracting the beam at a predetermined angle, and an outer clad layer proximate the grating and so as to establish at least one propagating mode characterized by an angle, the predetermined angle being matched to such angle.
