We have developed a 1 Hz relative linewidth Er:fiber comb utilizing a semiconductor saturable absorber mirror. We have also developed an iodine-stabilized laser at telecom wavelengths and achieved high frequency stability, which can be used as a frequency reference for optical frequency combs. Furthermore, we have developed frequency-stabilized lasers for our Yb cold atom experiments. Recently, optical frequency combs and frequency-stabilized lasers are also used in quantum information experiments. We have improved the dual-band stabilization for twin-field quantum key distribution using laser frequency stabilization. We have also proposed and demonstrated a novel phase stabilization method for single-photon interference.
