Abstract

Germania-glass-core silica-glass-cladding single-mode fibers (Δn as great as 0.143) with a minimum loss of 20 dB/km at 1.85 μm were fabricated by modified chemical-vapor deposition. The fibers exhibit strong photorefractivity, with type Ha index modulation of 2 X 10-3. A Raman gain of 300 dB/(kmW) was determined at 1.12 μm. Only 3 m of such fibers is sufficient for constructing the 10-W Raman laser at 1.12 μm with a 13-W pump at 1.07 μm.
