Diode-pumped 88-fs Kerr-lens mode-locked Yb:Y₃Ga₅O₁₂ crystal laser

We realized a stable Kerr-lens mode-locked operation in a diode-pumped Yb:Y₃Ga₅O₁₂ laser. Pulses as short as 88 fs at the center wavelength of 1042 nm were obtained at a repetition rate of 159.3 MHz. The maximum output power was 104 mW under the incident pump power of 3.9 W. By comparing the mode-locked characteristics under different output transmissions, we obtained pulses with the highest output power of 330 mW and a duration of 149 fs. To the best of our knowledge, this is the first demonstration of a Kerr-lens mode-locked Yb:Y₃Ga₅O₁₂ laser.
