The coupled-mode equations for two-wave mixing are extended to include light-scattering noise and are solved using the stochastic noise model. Solutions are given for amplitude, phase, and output-power fluctuations during weak-signal amplification. Minimum power requirements for low-noise signal amplification in Kerr media are determined.
