摘要：

An　all-fiber　continuous-wave　thulium-doped　fiber　laser　with　narrow　linear　width　based　on　a　master　oscillator　power　amplifier　(MOPA)　system　that　consists　of　a　seed　source　and　two-stage　thulium-doped　all-fiber　amplifiers　pumped　by　fiber-pigtailed　multimode　diodes　at　793　nm　is　reported.　The　maximum　output　power　is　120　W　with　a　slope　efficiency　of　60%　after　the　seed　source　amplified　by　a　two-stage　thulium-doped　amplifier.　The　center　wavelength　is　1986　nm　and　3　dB　spectral　width　is　only　0.48　nm.　The　maximum　output　power　is　currently　limited　by　available　pump　power.　In　addition,　a　broadband　thulium-doped　superfluorescent　source　with　average　output　power　of　122　W　based　on　the　same　MOPA　configuration　is　reported.　The　center　wavelength　is　1990　nm　and　3　dB　spectral　width　is　25　nm.
