The Anti-stokes Wave of Ultrafast Stimulated Raman Scattering in Single Mode Fibers

由光纤中光的基本传输方程出发 ,利用慢变振幅近似 ,给出了包含反斯托克斯波的光纤超快受激拉曼散射的耦合波方程。以此为基础讨论连续、超快受激拉曼散射中泵浦波、斯托克斯和反斯托克斯波的耦合 。

Couple wave equation (four wave mixing equation) was deduced from the basic propagation equation in the optical fibers by adopting of slowly varying envelope approximation. This equation could be used to describe ultrafast pulse even ps range. Based on this, the couple of pump wave, stokes wave and anti stokes wave in ultrafast continual stimulated Raman scattering were discussed. The effect of phase matching and group velocity matching on ultrafast stimulated Raman scattering and anti stokes wave in single mode optical fibers were analysized.
