Abstract
Two independent mode-locked femtosecond lasers are synchronized to an unprecedented precision. The remaining rms timing jitter betweenthe lasers is 4.3 fs observed within a 160 Hz bandwidth over tens of seconds, or 26 fs within a 50 kHz bandwidth. The novel configuration of multi-state phase locked loops helps to preserve this ultrahigh timing resolution throughout the entire tuning range of the pulse repetition period (10 ns). We have also demonstrated that such synchronization can be achieved with two lasers at different repetition frequencies.Citation
