We have experimentally demonstrated an efficient all-fiber passively Q-switched Yb-doped fiber laser with Samarium doped fiber as a saturable absorber. Average output power of 3.4Ã¢Â€Â‰W at a repetition rate of 250Ã¢Â€Â‰kHz and a pulse width of 1.1 microseconds was obtained at a pump power of 9.0Ã¢Â€Â‰W. By using this fiber laser system and an MgO-doped congruent periodically poled lithium niobate (MgO:c-PPLN), second harmonic generation (SHG) output at 532Ã¢Â€Â‰nm was achieved at room temperature. The conversion efficiency is around 4.2% which agrees well with the theoretical simulation
