摘要：

A　high-power　all-fiber　mid-infrared　(mid-IR)　supercontinuum　(SC)　generation　in　a　single-mode　ZBLAN　fiber　pumped　by　amplified　noise-like　pulses　is　reported.　The　mid-IR　SC　system　is　a　2　μm　master　oscillator　power　amplifier　(MOPA)　construction　including　a　seed　source　and　two-stage　single-mode　thulium-doped　fiber　amplifier　(TDFA)　followed　by　a　single-mode　ZBLAN　fiber.　A　noise-like　pulse　fiber　oscillator　with　wavepacket　width　of　1.4　ns　and　repetition　rate　of　3.36　MHz　at　1966　nm　is　used　as　a　seed　source　of　mid-IR　SC　system.　In　the　last　stage　TDFA,　a　SC　covering　from　1.9　to　2.4　μm　with　maximum　output　power　of　28.5　W　is　generated.　Then,　the　output　SC　of　TDFA　is　injected　into　a　10　m　single-mode　ZBLAN　fiber　for　further　spectrum　broadening.　At　last,　a　mid-IR　SC　covering　from　1.9　to　3.62　μm　with　the　maximum　output　power　of　14.3　W　is　generated.　©,　2015,　Science　Press.　All　right　reserved.
