Abstract：

We　proposed　and　demonstrated　an　all　fiber　passively　Q-switching　laser　to　generate　cylindrical-vector　beam,　a　two　dimensional　material,　tungsten　disulphide　(WS2),　was　adopted　as　a　saturable　absorber　inside　the　laser　cavity,　while　a　few-mode　fiber　Bragg　grating　was　used　as　a　transverse　mode-selective　output　coupler.　The　repetition　rate　of　the　Q-switching　output　pulses　can　be　varied　from　80　kHz　to　120　kHz　with　a　shortest　duration　of　958　ns.　Attributed　to　the　high　damage　threshold　and　polarization　insensitivity　of　the　WS2　based　saturable　absorber,　the　radially　polarized　beam　and　azimuthally　polarized　beam　can　be　easily　generated　in　the　Q-switching　fiber　laser.　©　2015　AIP　Publishing　LLC.
