Abstract

This study presents the development of a digital locking system for a mode-locked laser with a 50MHz repetition rate. Compared to traditional analog circuit locking systems, our digital approach provides a routine to significantly reduce the system footprint and complexity while achieving similar locking performance. Our digital laser servo provides a two- order-of-magnitude reduction in Allan deviation compared to the free-running state of the laser.
