  1. Secondly, basing on the theory of on - off gain of small signal, the raman gain coefficient for frequency shift between 0. 5 and 20 thz of standard sigle mode optical fiber is measured by pump - probe method through a super luminescent diode ( sld ) as a broadband small signal probe source. thirdly, numerical simulation analysis of gain characteristic of raman fiber amplifier for c band wdm signal light is made according to the raman gain coefficient of the fiber measured before through target and four rank runge - kutta method. at the invariability of wavelength and maximum power of each of two pumps, schematic of powers of two pumps for best flatness on c band wdm optical gain was found out, at the same time, the factors of resulting in gain saturation is analyzed, too

    本文首先應用經典的磁理論對拉曼光纖放大器的工作制進行了分析,然後,根據小信號理論推出的開關增益求出了光纖拉曼增益系數的表達式,採用泵浦-探測波的方法,利用輻射激光二體( superluminescentdiode簡稱sld )作為探測光源,測量了所用標準模光纖頻移為0 . 5 - 20thz的拉曼增益系數,之後根據所測得的光纖的拉曼增益系數譜對應用該類光纖構成的放大c波段wdm光信號的拉曼光纖放大器的增益特性採用打靶法和四階龍格- - -庫塔進行了數值計算,在給定了兩個泵浦光源的波長和最大功率后,找出了反向泵浦情況下使c波段wdm光源增益最平坦的兩個泵浦的各自最佳功率,同時也分析了致信號光飽和的原因。
