| 摘 要： | 从理论推导了非线性系数逐渐增加的非一致性光纤(非线性渐增光纤,NIF)也可以压缩脉冲的结论,并由仿真证明了这一理论结论,理论和仿真符合得很好.仿照传统脉冲压缩的研究方法,分析了这一新方法压缩脉冲的能力、压缩比以及基座能量等性能,结果表明,双曲函数的渐增形式更适于此类脉冲压缩.和已有的色散渐减方法进行了比较,结果表明,非线性渐增的方法压缩脉冲所需光纤长度更短、质量更好.

| Abstract: | A new method of stilton compression by using nonlineary-increasing fiber is proved according to the theoretical de duction and numerical simulation. Characteristics of the yielded pulse such as the compression ratio and pedestal energy are anlayzed. Results show that hyperbolic profile is more suitable to this method. And through comparison,it is found that with a shorter length of fiber the new method performs a better compression than dispersion-decreasing method. |
