摘　　要：We demonstrate the generation of a unique regime of multiple solitons in a Tm-doped ultrafast fiber laser at~1938.72 nm.The temporal pulse-to-pulse separation among the multiple solitons,10 in a single-pulse bunch,increases from 0.89 ns to1.85 ns per round trip.In addition,with the increasing pump power,the number of bunched solitons increases from 3 up to 24linearly,while the average time separation in the soliton bunch varies irregularly between~0.80 and~1.52 ns.These results contribute to a more profound comprehension of nonlinear pulse dynamics in ultrafast fiber lasers.
