A side-pumped fiber laser includes an optical fiber having a core (18) and a cladding (20). The core (18) has an index of refraction n1, greater than that of the cladding (20), n2. The fiber laser further includes a coupling window (22) integrally formed within a channel formed in an upper side of the fiber cladding. The coupling window has an index of refraction n3, greater thant n1. The fiber laser further includes a laser light source (14), such as a laser diode bar(s), whose beam(s) are directed through the coupling window so as to couple the light directly to the fiber core (18). Bragg gratings (26) may also be included between the coupling window (22) and a reflective window (28). |
