摘    要:将再生锁模光纤激光器(RMLFL)输出的约5.8 ps脉宽的高质量无啁啾双曲正割脉冲,通过掺铒光纤放大器(EDFA)放大后注入4.28 km长的色散平坦光纤(DFF)中,利用二阶孤子压缩效应成功地将脉冲压缩到1.74 ps,压缩比为3.3,与理论计算结果完全一致。与基于色散渐减光纤(DDF)的绝热孤子压缩(ASC)方案相比,该方案在同样的孤子阶数下大大降低了入射功率,而且色散平坦光纤的非色散渐减特性决定了它对于不同波长、不同脉宽的输入都可以通过调整输入脉冲功率和选取合适的光纤长度来配合满足压缩条件。虽然压缩因子不大,但基本能满足需求。

关 键 词:导波与光纤光学  高阶孤子  色散平坦光纤  再生锁模光纤激光器

Abstract:Using second-order soliton compression effect in 4.28 km dispersion flattened fiber(DFF),the(5.8 ps) pulse with the repetition rate of 10 GHz generated from a regeneratively mode-locked fiber laser(RMLFL) was compressed into pulse with pulse-width of(1.74 ps.) The compression factor was 3.3.The experimental results agree well with the theoretical results.Compared to adiabatic soliton compression(ASC) based on dispersion decreasing fiber(DDF),this scheme can greatly lower the input power for the same soliton order numbers.Moreover,for the input pulses with different wavelength and pulse width,compression condition can be satisfied by adjusting input power and choosing proper fiber length,which is determined by the non-dispersion-decreasing characteristics of DFF.Despite the compression factor is small,it still meets requirement.
Keywords:guided wave and fiber optics  high-order soliton  dispersion flattened fiber  regeneratively mode-locked fiber laser
