Abstract
A side-pumped fiber laser includes an optical fiber having a core and a cladding. The core has an index of refraction n and the cladding has an index of refraction n , wherein n is greater than n . The fiber further includes a coupling window integrally formed within a channel formed in an upper side of fiber cladding. The coupling window consists of an optical material having an index of refraction n wherein n is greater than n . The fiber laser further includes a laser light source that is directed through the coupling window wherein laser light is directly coupled into the core of the fiber. The fiber of the fiber laser also preferably includes Bragg gratings written into the core beneath the coupling window and a reflective material disposed in a second window formed beneath the Bragg gratings.
