Chinese Abstract

借助簡化的拉曼光纖放大器數學模型,利用平均功率法和打靶法分別計算出了不同參數下多波長泵浦的拉曼增益。在對增益圖分析的基礎上,可以得到多波長激光器作為拉曼泵浦,它的三個典型參數(波長間隔、初始功率和光波個數)中的任一參數的變化都會引起拉曼增益的波動,並且為了達到增益均衡的目的,波長間隔不能太小、光波個數不易太少以及不能片面追求高初始功率。與多泵浦系統相比,它需要優化的參數大為減少,運算速度提高,並用一個泵浦源就能滿足需求,降低了成本,具有發展的潛力。

English Abstract

Based on the simple and effective modle of Raman fiber amplifier, Raman gains under different parameters are computed with the help of average power and shooting method. Result that Raman gain will change with the change of one of the three typical parameters (interval of wavelength, input power and number of wavelength) is got based on the analysis of Raman gain figures, and for the purpose of gain flatten, interval of wavelength shouldn't be too small, number of wavelength shouldn't be too little and input power should be proper. Compared with system using several pumps, it has higher efficiency and lesser parameters that should be optimized, and it meet the demands with the help of only one pump, so it has the potentiality of development.
