METHODS AND SYSTEMS FOR FREQUENCY STABILISATION OF MULTIPLE LASERS

摘要

A METHOD FOR FREQUENCY STABILISATION OF A PLURALITY OF LASERS, INCLUDING: GENERATING A CORRESPONDING PLURALITY OF RADIO-FREQUENCY (RF) SIGNALS REPRESENTATIVE OF FREQUENCY FLUCTUATIONS IN THE RESPECTIVE LASERS USING A SHARED FREQUENCY REFERENCE; GENERATING A CORRESPONDING PLURALITY OF PHASE SIGNALS FROM THE RF SIGNALS; AND CONTROLLING THE RESPECTIVE FREQUENCIES OF THE LASERS, USING THE PHASE SIGNALS, TO REDUCE THE FREQUENCY FLUCTUATIONS.
