Abstract：

High　average　power　linearly-polarized　nanosecond-pulsed,　modulated　diode　seeded　thuliumdoped　fiber　laser　based　on　master　oscillator　power　amplifier　(MOPA)　system　is　reported.　The　modulated　seed　laser　delivers　20　ns　pulses　with　tunable　repetition　rate　from　200　kHz　to　1　MHz.　The　MOPA　yields　100　W　average　output　power　at　200　kHz　repetition　rate.　The　pulse　duration　reduces　to　6　ns　during　amplification　due　to　gain　reshaping　effect,　which　lead　to　a　higher　peak　power　of　83　kW　with　pulse　energy　of　0.5　mJ.　To　the　best　of　our　knowledge,　this　is　the　first　demonstration　of　average　output　power　exceeding　100　W　from　a　linear　polarization,　thulium　doped　fiber　laser　using　modulated　diode　as　a　seed.　©,　2015,　Science　Press.　All　right　reserved.
