| 摘 要： | 利用位于正常色散区间的色散递减光纤为介质,采用分步傅立叶方法数值研究了脉冲在正常色散区间色散递减光纤中传输时抛物线脉冲的产生过程。数值计算表明:当脉冲在位于正常色散递减光纤中传输时,脉冲逐渐演化为抛物线形状,并且在脉冲的中心形成规则的线性啁啾,利用此啁啾可实现对脉冲的进一步压缩,得到高质量超短脉冲。

| Abstract: | A novel designed model of parabolic pulse generation based on the normal dispersion decreasing fiber has been presented in the paper.Numerical simulation shows that a parabolic pulse in shape whose central part is linear up-chirp can be get when a Gaussian pulse propagating in the ND-DDF.High quality compressed pulse can be get with this linear up-chirp parabolic pulse. |

| Keywords: | normal dispersion dispersion decreasing fibers parabolic pulse linear chirp optical pulse compression |
