摘　　要：As a universal phenomenon in nonlinear optical systems,intermittency is usually accompanied by the coherence loss such as soliton explosions in fiber lasers.Based on real-time spectroscopy,we revealed the coherent dissipative soliton intermittency in normal-dispersion fiber lasers.By increasing the pump strength,the intermittency transforms from the transient pulsation to the bo-stable soliton.It is demonstrated that the slow-gain effect dominates such coherent intermittency.Our results provide novel insights into laser physics,offering a promising approach for studying the bi-stable dissipative soliton.
