Abstract

Abstract

We demonstrated a self-starting mode-locked Ti:sapphire laser by using a synchronously pumping scheme with a frequency doubled femtosecond Yb fiber laser. By carefully adjusting the cavity length of the Ti:sapphire oscillator to match the fiber laser, the mode-locking operation can start automatically. In the experiment, a femtosecond ytterbium-doped fiber laser at 520 nm was used to pump the Ti:sapphire laser synchronously. Under the 3.4 W pump power, 130 mW/17 fs mode locked laser pulses were obtained from the Ti:sapphire laser at the repetition rate of 75 MHz. It not only solves the difficulty of conventional Ti:sapphire oscillator for no-starting mode locking, but also synchronously supplies three femtosecond laser beams at central wavelengths of 1040, 800 and 520 nm, which paved an advanced way for further studies of coherent combination and optical parametric amplification.
