摘      要：Real-time spectroscopy based on an emerging time-stretch technique can map the spectral information of optical waves into the time domain,opening several fascinating explorations of nonlinear dynamics in mode-locked ***,the self-starting process of mode-locked lasers is quite sensitive to environmental perturbation,which causes the transient behaviors of lasers to deviate from the true buildup process of *** optimize the laser system to improve its stability,which suppresses the Q-switched lasing induced by environmental ***,therefore,demonstrate the first observation of the entire buildup process of solitons in a mode-locked laser,revealing two possible pathways to generate the temporal *** pathway includes the dynamics of raised relaxation oscillation,quasimode-locking stage,spectral beating behavior,and finally the stable single-soliton *** other pathway contains,however,an extra transient bound-state stage before the final single-pulse modelocking ***,we propose a theoretical model to predict the buildup time of solitons,which agrees well with the experimental *** findings can bring real-time insights into ultrafast fiber laser design and optimization,as well as promote the application of fiber laser.
