Mode-locked laser as a combined radio-grequency and optical clock, stabilized to a reference cavity, and calibrated through coherent interaction with rubidium

摘要

The feasibility of ultrafast (10 THz) communication by time multiplexing using femtosecond pulses is discussed. Such a system calls for stable mode-locked sources in frequency and repetition rate, that can be synchronized with sub fs jitter. Preliminary experiments and theory show this goal to be achievable.
