Abstract

Measurement and control of the carrier frequency, phase, and repetition rate of ultra-short light pulses is important in a wide variety of applications. Reduction of the pulse train jitter and/or synchronization of the repetition rates is required in experiments involving multiple lasers such as ultra-fast communication systems and pump-probe experiments. In the field of frequency metrology, the femtosecond laser has emerged as an indispensable tool for bridging large frequency gaps and may open up the way towards all optical clocks We demonstrate that a Fabry-Perot interferometer can provide the essential carrier frequency and phase information to stabilize mode-locked pulse trains
