Query: Incoherently pumped high-power linearly-polarized single-mode random
  fiber laser: experimental investigations and theoretical prospects   We present a hundred-watt-level linearly-polarized random fiber laser (RFL)
pumped by incoherent broadband amplified spontaneous emission (ASE) source and
prospect the power scaling potential theoretically. The RFL employs half-opened
cavity structure which is composed by a section of 330 m polarization
maintained (PM) passive fiber and two PM high reflectivity fiber Bragg
gratings. The 2nd order Stokes light centered at 1178 nm reaches the pump
limited maximal power of 100.7 W with a full width at half-maximum linewidth of
2.58 nm and polarization extinction ratio of 23.5 dB. The corresponding
ultimate quantum efficiency of pump to 2nd order Stokes light is 89.01%. To the
best of our knowledge, this is the first demonstration of linearly-polarized
high-order RFL with hundred-watt output power. Furthermore, the theoretical
investigation indicates that 300 W-level linearly-polarized single-mode 1st
order Stokes light can be obtained from incoherently pumped RFL with 100 m PM
passive fiber.
