| 摘 要： | 采用Rugate膜系理论，分别根据钛宝石和钕玻璃介质增益窄化的特点，合理选择补偿增益窄化的调制函数，优化设计出了分别用于补偿钛宝石系统和钕玻璃系统增益窄化效应的Rugate滤波器.由普通均匀多层膜的特征矩阵方法近似分析了设计出的Rugate滤波器的光谱响应，数值模拟了Rugate滤波器的光谱补偿效果.结果显示，能比较好的符合光谱补偿的要求，可以用作补偿增益窄化效应的光谱调制滤波器.关键词：超短脉冲增益窄化光谱补偿Rugate滤波器

| Abstract: | Two Rugate filters for compensating gain narrowing are designed separately based on the gain characteristics of Ti: sapphire amplifier and Nd: glass amplifier. The Gauss spectral shaping function is selected as the compensation modulation function. Characteristic matrix method is used to analyse the spectral response of the Rugate filter approximately. Amplification using Rugate filter spectral compensation is analysed numerically. Results show that they satisfy the compensation requirements well and can be used as the spectral compensation filters. |
