The experimental study on an all-fiber laser pulse amplifier system using homemade double-cladding Yb-doped fibers as gain media is presented. Secondary pulse phenomenon produced in the pulse amplifier system is analyzed and investigated. We find that the phenomenon depends a lot on the quality of splicing between different fibers and the amplification multiple. By controlling the pump power and amplification multiples of the amplifier and trying different splicing parameters, we can get stable high power pulse lasing output. Finally, using the Yb-doped double-cladding fiber(YDCF) and master oscillation power amplification (MOPA) techniques, a stable all-fiber pulse amplification system is obtained, with lasing wavelength at 1064 nm, 20 ns line-width pulses, average power of 2.4W and repetition rate of 50kHz.
