Abstract: We propose a scheme to suppress the laser phase noise without increasing the optomechanical single-photon coupling strength. In the scheme, the parametric amplification terms, created by Kerr and Duffing nonlinearities, can restrain laser phase noise… read more here.

Abstract: Abstract In order to achieve the coherent combining of two individual lasers, the relationship between two lasers should be determined. Since the phase noise is one of the primary reasons that cause the randomness of… read more here.

Abstract: The frequency stability of many optical atomic clocks is limited by the coherence of their local oscillator. Here, we present a measurement protocol that overcomes the laser coherence limit. It relies on engineered dynamical decoupling… read more here.
