We demonstrate the highly precise active-synchronization between two independent Ti: sapphire femtosecond oscillators. A combination of three phase locked loops, is used to control the synchronization between two laser pulseswhich gives a RMS timing jitter less than 30fs. With the technique of cavity length monitoring and autocontrol by a computerthis highly precise synchronization can be retained for more than 40 minutes.
