We report on hundred watts range ytterbium-doped all-fiber laser assembly based on the master oscillator power amplifier structure.It consisted of an oscillator and an amplifier with all-fiber components.And fiber fusion splice made the laser be an integrated fiber system.It generated up to 175.5 W of continuous- wave (CW) output power at 1085 nm with more than 75% extraction efficiency in the amplifier when the total coupled pump power into the double clad fiber was 270 W.
