    Optical clocks have many applications, from improved GNSS measurements to fundamental tests of general relativity, but their frequency stability is limited by quantum noise and the Dick effect. The authors present and demonstrate a method to estimate the phase of an optical clock laser beyond the laser coherence time that can be used to improve the stability of these devices for applications in metrology and the search for new physics.
