摘要/Abstract

摘要： 根据熔石英拉曼增益曲线的特点, 将研究的拉曼谱范围分为一定数目小的频率区间, 每个区间的Stocks光被所有高频区间的光泵浦, 并作为低频区间Stocks光的泵浦光, 它们之间的相互作用遵循耦合波微分方程.对所有区间的微分方程组求解计算出不同长度光纤在不同泵浦光强下输出端的拉曼散射谱, 对其进行分析得出不同情况下受激拉曼散射的阈值.

Abstract: According to characteristic of the Raman gain curve,the Raman spectral region of interest was divided into a number of small frequency intervals.The Stocks spectrum of every frequency interval was pumped by those of higher frequency and pumped those of lower frequency.The effcet between them can be described by coupled differential equation.Solving the equationgroup of the entire frequency range, the Raman spectrum in different length fiber pumped by diff-
erent intersity be calculated and the threshold pump intensitybe obtained by study the calculated spectrum.

Key words: monomode optical fibers, nonlinear effect, stimulate Raman scattering
