Multiple polarization dynamic patterns of vector solitons, including fundamental solitons, bunched solitons, loosely or tightly bound states and harmonic mode locking have been observed experimentally in an erbium-doped fiber ring laser with graphene as a saturable absorber. By carefully adjusting the pump power and the orientation of the intra-cavity polarization controller, either polarization rotation or polarization locked operation have all been achieved for the above vector solitons. This is the first time that high order harmonic mode locking of polarization rotation vector solitons has been achieved. The signal to noise ratio of our system was ~51 dB, which indicates that the laser operated with high stability.
在以石墨烯作为可饱和吸收体的掺铒光纤环形激光器中,已通过实验观察到矢量孤子的多种偏振动态模式,包括基孤子、成束孤子、松散或紧密束缚态以及谐波模式锁定。通过仔细调整泵浦功率和腔内偏振控制器的取向,上述矢量孤子均实现了偏振旋转或偏振锁定操作。这是首次实现偏振旋转矢量孤子的高阶谐波模式锁定。我们系统的信噪比约为51 dB,这表明激光器以高稳定性运行。
