摘要：

A　high-power　all-fiber　mid-infrared　supercontinuum　laser　source　that　consists　of　a　1.55　μm　nanosecond-pulsed　erbium-doped　fiber　laser,　a　cladding-pumped　thulium-doped　fiber　amplifier　and　a　segment　of　single-mode　ZBLAN　fiber　is　reported.　Firstly,　the　pulse　breaks　up　through　modulation　instability　and　the　laser　shifts　to　a　longer　wavelength　through　Raman　processes　in　the　single-mode　fiber.　Secondly,　the　nanosecond　pulses　are　amplified　through　a　thulium-doped　fiber　amplifier.　Finally,　the　output　spectrum　from　the　thulium-doped　fiber　amplifier　is　extended　to　the　mid-infrared　wavelength　by　using　a　segment　of　single-mode　ZBLAN　fiber.　The　output　power　from　the　ZBLAN　fiber　is　2.2　W　with　the　launched　pump　power　of　3.95　W　at　2.0　μm　wavelength　region,　the　emission　spans　the　wavelength　range　from　1.9　μm　to　3.75　μm　with　a　10　dB　bandwidth　of　greater　than　1600　nm.　In　addition,　a　higher　output　power　mid-infrared　supercontinuum　laser　source　is　achieved　by　increasing　the　average　output　power　of　the　thulium-doped　fiber　amplifier.　The　ZBLAN　fiber　produces　an　average　output　power　of　16.2　W　with　the　coupling　pump　power　of　21　W　at　2.0　μm　wavelength　region,　the　emission　spans　the　wavelength　range　from　1.9　μm　to　3.5　μm.
