All-fiber low-noise high-power femtosecond Yb-fiber amplifier system seeded by an all normal dispersion fiber oscillator

Cataloged from PDF version of article.We report an all-fiber, high-power, low-noise ampli-fier system seeded by an all-normal-dispersion-mode-locked Ybdoped fiber laser oscillator. Up to 10.6 W of average power is obtained at a repetition rate of 43 MHz with diffraction-limited beam quality. Amplified pulses are dechirped to sub-160-fs duration in a grating compressor. It is to our knowledge the first high-power source of femtosecond pulses with completely fiber-integrated amplification comprising commercially available components. Longterm stability is excellent. Short-term stability is characterized and an integrated laser intensity noise of
