Abstract
A fiber, with enhanced stimulated Raman scattering for use in light amplification, transmits light wave energy in a single mode. The fiber includes a cylindrical core of light transmitting material doped with a substantial concentration of GeO.sub.2, an inner cladding of light transmitting material doped with a sizable concentration of GeO.sub.2 (but less than the substantial concentration) surrounding the core, and an outer cladding of GeO.sub.2 -free material surrounding the inner cladding.
