The passive mode-locked fiber laser based on the nonlinear polarization rotation principle is applied as the master oscillator. The repetition rate and pulse width of the pulse are 30 MHz and 265 fs, respectively. After stretching the pulse width to 100 ps via the chirped fiber Bragg grating, the signal is amplified by one stage of 10 m-core-diameter fiber pre-amplifier and one stage of 50 m-core-diameter fiber power amplifier. The output average power is 10 W with a slope efficiency of 41.5%. And the pulse is compressed to 594 fs via a bulk grating compressor.
