Abstract :
Many locking approaches have been exploited to stabilize the mode-locked laser (MLL), helping to generate high-stable microwave sources. We present a novel miniaturized stabilization scheme for MLL, based on a rubidium coherent population trapping (CPT) atomic resonator. By directly frequency-locking the repetition rate of the MLL to a 85Rb CPT resonance, we demonstrate a very small stabilization system (length of 5 cm, width of 5 cm and height of 2.2 cm) for MLL with a long-term instability of ~3×10-12.
