Abstract We demonstrate an octave?spanning Kerr-lens mode-locked Ti:sapphire laser with double-chirped mirrors (DCMs), BaF2 wedges and plate, which generates laser pulses in the spectrum range from 600 nm to 1200 nm at -45 dB below the maximum and the duration of 8.5 fs at the repetition rate of 80 MHz. The average output power is 100 mW under 5 W pump power. By carefully adjusting the insertion of BaF2 wedges and the optimization position of Ti:sapphire crystal in the cavity, we can obtain the smooth swings in the interferometric autocorrelation trace due to good third-order dispersion compensation.
