我们描述了石英光纤中多个振动模式的受激拉曼增益谱和拉曼响应函数的模型。我们基于以前的光谱数据[J.opt.SoC。上午好。B1,652(1984)和J.Opt.SoC。上午好。B6,1159(1989)]，并扩展了先前提出的模型[Appl.Opt.21,359(1982)]利用阻尼振子的不均匀分布。该模型提供了简单的拉曼响应函数的解析表达式和易于数值计算的拉曼增益谱的表达式。
We describe a model for the stimulated Raman gain spectrum and the Raman response function in silica fiber using multiple vibrational modes. We base the model on previous spectroscopic data [J. Opt. Soc. Am. B1, 652 (1984) and J. Opt. Soc. Am. B6, 1159 (1989)] and extend an earlier proposed model [Appl. Opt.21, 359 (1982)] by making use of an inhomogeneous distribution of damped oscillators. The model provides a simple analytical expression for the Raman response function and an expression for the Raman gain spectrum that is easy to evaluate numerically.
