Abstract
A self-starting femtosecond harmonic mode-locked Ti:sapphire laser is demonstrated, pumped by a 75.5 MHz frequency-doubled mode-locked Yb:KGW oscillator. The maximum average output power is 256 mW at the central wavelength of 811 nm with 3.6 W pump power. A pulse duration as short as 12.7 fs is obtained by using a 3% output coupler. The repetition rate of the Ti:sapphire laser is set to be 151 MHz, which is successfully locked to the twice that of the pump laser.
