我们报告了对通过非线性放大环形镜锁定的全偏振ER纤维振荡器模式的色散管理的研究，该模式在带有两个输出端口的九型腔构型中。在-0.034 PS2至+0.006 PS2的净腔分散液中研究了激光的性能。我们表明，在两个图九输出中，脉冲的光谱和时间阶段都具有明显不同的特征。激光输出之一为脉冲提供了明显更好的质量。尽管如此，排斥输出还提供了具有宽光谱的超短脉冲。直接从接近零分散体状态下的激光器中产生了脉冲短于79 Fs，能量为83 PJ。
We report an investigation of dispersion management of an all-polarization-maintaining Er-fiber oscillator mode-locked via a nonlinear amplification loop mirror in a figure-nine cavity configuration with two output ports. The performance of the laser was investigated within the net cavity dispersion ranging from -0.034 ps2 to +0.006 ps2. We show that the spectral and temporal phase of the pulses at both figure-nine outputs have clearly different characteristics. One of the laser outputs provides pulses with significantly better quality; nonetheless, the rejection output also offers ultrashort pulses with broad spectra. Pulses as short as 79 fs with an energy of 83 pJ were generated directly from the laser in the near-zero dispersion regime.
