title: Raman gain saturation at high pump and Stokes powers.
abstract: Raman gain spectral profile has been measured in a phosphosilicate fiber at high pump and Stokes (signal) wave powers. It has been shown that the profile saturates homogeneously. The main saturation mechanism is proved to be the pump depletion, i.e., Raman gain coefficient gR does not depend on the pump and signal wave power up to the level of ~ 3 W.
