摘　　要：在非线性偏振旋转锁模的掺铥环形光纤激光器中实现了非对称的h型脉冲输出,同时针对实验进行了数值仿真。考虑到三阶色散的累积影响,得到了与实验结果一致的h型脉冲信号,由此发现三阶色散促进了脉冲拖尾的形成。Output of h-shaped pulses is realized in a mode-locked Thulium-doped fiber ring laser with the nonlinear polarization rotation technique, simultaneously, a simulation is carried out for the ex-periment. In consideration of accumulated impact of the third order dispersion, the h-shaped pulses are generated by computation, consistent with the experimental results. It is found then, the third order dispersion boosts the forming of the h-shaped pulses.
