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 10 0m和 5 0 0m的色散缓变光纤 ,成功地将分布反馈激光器输出的 4 4 ps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 。
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.
