Relying on the nonlinear multimode interference in multimode fibers and the nonlinear polarization rotation, these two mode-locked techniques are combined in our proposed fiber laser. Stable optical soliton and multi-pulse regimes with a constant frequency of 11.44 MHz have been generated experimentally. Through altering intra-cavity conditions, bound-state pulses with diverse properties are observed. To the best of our knowledge, the obtained bound-state pulse constituted by more than thirty sub-pulses is achieved for the first time. Moreover, the center wavelength of bound-state pulse could be switched in a certain range covering the entire C band.
基于多模光纤中的非线性多模干涉和非线性偏振旋转，这两种锁模技术被结合到我们提出的光纤激光器中。实验上已经产生了频率为11.44 MHz的稳定光孤子和多脉冲状态。通过改变腔内条件，观察到了具有不同特性的束缚态脉冲。据我们所知，首次获得了由三十多个子脉冲构成的束缚态脉冲。此外，束缚态脉冲的中心波长可以在覆盖整个C波段的一定范围内切换。
