Abstract We demonstrate an experimental setup of a tunable ultrafast laser source by sum-frequency generation (SFG) between a mode-locking Ti:sapphire laser and a Nd:YVO4 laser. The generated wavelength by SFG is tunable from 450 nm to 480 nm with timing jitter no more than 1 ps. The average output power is over 20 mW and the maximum is about 30 mW at 457 nm. This ultrafast laser is a simple and easy tuning source applied to some pump-probe spectroscopy and ultrafast dynamics experiments.
