Abstract：

A　Thulium-Doped　fiber　chirped　pulse　amplifier　(FCPA)　is　presented　and　used　to　pump　a　ZrF4-BaF2-LaF3-AlF3-NaF　(ZBLAN)　fiber　for　mid-infrared　supercontinuum　generation.　The　FCPA　delivers　10　W　average　power　at　repetition　rate　of　10　MHz　with　pulse　width　of　252　fs.　The　pulses　are　coupled　into　10　m　ZBLAN　fiber　using　an　aspheric　lens.　Maximum　output　power　of　800　mW　corresponding　to　pulse　energy　of　80　nJ　has　been　obtained　with　5　dB　spectrum　ranging　from　2μm　to　3.5　μm,　which　is　limited　by　the　low　pump　coupling　efficiency　of　∼10%　at　this　time.　©　2015　by　the　Canadian　Institute　of　Mining,　Metallurgy　&　Petroleum.
