We demonstrate an experimental observation of soliton rains in an all normal dispersion Yb-fiber laser. The cavity consists of a narrow bandwidth filter and a birefringent plate (BP) filter. Soliton rain is obtained in the weak mode-locking regime, while multisolitons behaving as soliton bunches and harmonic mode-locking under strong mode-locking are also observed. Distinctive multisoliton interactions are observed via changing the pump power and adjustment of the waveplates as well as the BP. To the best of our knowledge, this is the first demonstration of soliton rains in normal dispersion fiber lasers.
我们在全正色散 Yb 光纤激光器中演示了孤子雨的实验观测。该腔由一个窄带宽滤波器和一个双折射板（BP）滤波器组成。在弱锁模状态下获得了孤子雨，而在强锁模下，多孤子表现为孤子束和谐波锁模。通过改变泵浦功率以及波片和 BP 的调整，观察到了独特的多孤子相互作用。据我们所知，这是正色散光纤激光器中孤子雨的首次演示。
