Abstract
Abstract PURPOSE:To decrease light loss by extremely diminishing transition metal impurities and residual OH radicals. CONSTITUTION:A core having a high refractive index and a clad having a refractive index lower than the index of the core are formed by SiO2 and P2O5 having high purity. The core contains P2O5 in 10mol%. Light loss can be reduced by using an optical fiber formed in this manner as a laser medium for a fiber raman laser.
