We demonstrated a hybrid ceramic master-oscillator high-power fiber amplifier with a diode-pumped Yb:YAG ceramic laser as the seeding oscillator, which was passively mode-locked at 103.29 MHz repetition rate around 1031 nm by using a semiconductor saturable absorption mirror, and a two-stage double-clad photonic crystal fiber amplifier, which power-scaled the ceramic laser oscillator up to an average power of 303 W. The amplified pulses were further compressed to 237 and 418 fs at 50 and 150 W output powers, respectively. The compressed pulses exhibited about 0.05% deviation from the Gaussian fit, implying that the high-power fiber amplification induced neither observable temporal and spectral distortion nor significant nonlinear de-chirping of the chirped pulses.
