摘    要:报道了色散缓变光纤中超短光脉冲压缩效应的实验结果。采用两段长度分别为100m和500m的色散缓变光纤,成功地将分布反馈激光器输出的4.4ps光脉冲压缩到1.1ps和830fs,脉冲压缩比分别为4.0和5.3。研究还发现,色散沿纵向变化较慢的光纤有利于脉冲的进一步压缩,理论分析与实验结果一致。

关 键 词:超短光脉冲  色散缓变光纤  绝热压缩  光脉冲产生  脉冲压缩  非线性光学

Abstract:The adiabatic compression of ultrashort pulses from a DFB laser operating at 1550 nm in the fibers with slowly decreasing dispersion (FSDD) is investigated. High quality soliton compressions from 4.4 ps down to 1.1 ps in a 100 m FSDD and from 4.4 ps down to 830 fs in a 500 m FSDD are obtained. Furthermore, the results show that FSDD with more slowly decreasing can benefit to the pulse compression. Theoretical analyses are in good agreement with experimental results.
Keywords:decreasing  dispersion fiber  adiabatic compression  ultrashort pulse generation
