Abstract

We report on a high-repetition-rate self-mode-locking laser with a diode-pumped Yb:YAG ceramic thin disk. The third nonlinearity of the gain medium is exploited to achieve stable CW mode-locking operation without using any additional components in the cavity. The laser produces 60-ps pulses at the central wavelength of 1032 nm with a repetition rate of 3.8 GHz and an average power of 780 mW.
