Abstract

Abstract

The coherently coupled nonlinear Schrdinger (NLS) equation for laser propagating in birefringent fiber with parametric amplification and Raman scattering has been utilized. Considering higher-order dispersive, the gain spectra are studied under coaction of Raman scattering and parametric amplification when the pump wave polarization is oriented at 45 between the axes by quoting Lorentzian model of Raman gain spectra in high-birefringence fiber. The results show that the gain spectra are influenced by high-order dispersion under different input parameters (the input power, group velocity mismatch) in the anomalous(or normal) dispersion regime. The structure and intensity as well as width of gain spectra will change. The influence of high-order dispersion on the gain spectra cannot been neglected. The T-frequency pulses can been extracted when gain spectra are away from center frequency in high group-velocity mismatching zone.
