Kerr-lens mode-locked Yb:KYW laser at 4.6-GHz repetition rate.
We developed a laser-diode pumped, 4.6-GHz repetition-rate, Yb:KYW Kerr-lens mode-locked femtosecond oscillator. A bow-tie ring cavity generates an output power of 14.6 mW with a spectrum width of 11 nm at 1046 nm. To the best of our knowledge, this is the highest-repetition frequency in the laser-diode pumped femtosecond Kerr-lens mode-locked laser.
