摘要：

Germania-glass-core silica-glass-cladding single-mode fibers (An as great as 0.143) with a minimum loss of 20 dB/km at 1.85 mum were fabricated by modified chemical-vapor deposition. The fibers exhibit strong photo-refractivity, with type IIa index modulation of 2 x 10(-3). A Raman gain of 300 dB/(kmW) was determined at 1.12 mum. Only 3 in of such fibers is sufficient for constructing the 10-W Raman laser at 1.12 mum with a 13-W pump at 1.07 mum. (C) 2004 Optical Society of America.
