We report on the experimental observation of a new type of polarization-locked vector soliton in a passively mode-locked fiber laser. The vector soliton is characterized by the fact that not only are the two orthogonally polarized soliton components phase-locked, but also one of the components has a double-humped intensity profile. Multiple phase-locked high-order vector solitons with identical soliton parameters and harmonic mode locking of the vector solitons were also obtained in the laser. Numerical simulations confirmed the existence of stable high-order vector solitons in the fiber laser.
我们报道了在被动锁模光纤激光器中一种新型偏振锁定矢量孤子的实验观测结果。该矢量孤子的特点是,不仅两个正交偏振的孤子分量相位锁定,而且其中一个分量具有双峰强度分布。在该激光器中还获得了具有相同孤子参数的多个相位锁定高阶矢量孤子以及矢量孤子的谐波锁模。数值模拟证实了光纤激光器中稳定高阶矢量孤子的存在。
