A high-power diode-pumped passively mode-locked Yb:YAG ceramic laser was demonstrated. An average output power of 3.80 W with a pulse duration of 433 fs at a repetition rate of 90.9 MHz was obtained at a wavelength of 1050 nm using a 2% output coupler. A peak power of 96.5 kW was also obtained. To the best of our knowledge, these are the highest reported average power and peak power for a diode-pumped mode-locked Yb:YAG ceramic laser.

Key words: mode-locked lasers, diode-pumped lasers, ultrafast lasers, ytterbium laser, Yb:YAG
