Abstract

According to the coupling differential equations of the Stokes and anti-Stokes

the pump wave is linearly polarized and aligned with the

-axis direction. The gain coefficients have been reduced for the Stokes and anti-Stokes which simultaneously act of stimulated Raman scattering and parametric amplification in the same

polarization. The gain changes with mismatch

and normalized distance

z/L

in dispersion-decreasing fiber are obtained. It is observed that gain coefficient changes with the mismatch

is symmetrical when non-linear coefficient

in normal dispersion regime and anomalous dispersion regime. The gain will arise a peak and then with the

and

z/L

increases gradually reduce in the anomalous dispersion regime when non-linear coefficient

0. At the same time the feature about energy ratio of Stokes and anti-Stokes

reduced rapidly with increase of mismatch
