Revealing the Transition Dynamics from Q Switching to Mode Locking in a Soliton Laser

Liu, Xueming; Popa, Daniel; Akhmediev, Nail


Q switching (QS) and mode locking (ML) are the two main techniques enabling generation of ultrashort pulses. Here, we report the first observation of pulse evolution and dynamics in the QS-ML transition stage, where the ML soliton formation evolves from the QS pulses instead of relaxation oscillations (or quasicontinuous-wave oscillations) reported in previous studies. We discover a new way of soliton buildup in an ultrafast laser, passing through four stages: initial spontaneous noise, QS,...[Show more]
