Raman gain has been measured for five single-mode fibers with different relative index differences up to 1.0%. Using an experimental equation relating the mode-field radius to the relative index difference, a simple and practical relation between the Raman gain and the relative index difference has been established. The Raman-gain constant for pure SiO2 has been evaluated to be 7.4 X 10-14 m/W.
