Abstract：

High-pulse-energy　semiconductor　saturable　absorber　mirror　mode-locked　2.0　μm　thulium-doped　ultrafast　all-fiber　laser　is　reported.　Stable　mode-locked　pulse　train　occurred　at　1.8　W　incident　pump　power　and　the　pulse　repetition　rate　is　14.3　MHz　in　a　ring　cavity　configuration.　Increasing　the　incident　pump　power　to　3.8　W,　the　maximum　output　power　is　59　mW,　corresponding　to　the　maximum　single　pulse　energy　of　4.1　nJ.　The　pulse　width　is　measured　to　be　2.2　ps,　the　center　wavelength　and　the　spectral　bandwidth　are　2015　nm　and　2.9　nm　respectively.
