Phase-Coherent Multilevel Two-Photon Transitions in Cold Rb Atoms: Ultrahigh-Resolution Spectroscopy via Frequency-Stabilized Femtosecond Laser Public Deposited

Abstract
  • A two-photon transition in cold Rb atoms will be probed with a phase-coherent wide bandwidth femtosecond laser comb. Frequency domain analysis yields a high-resolution picture where phase coherence among various transition pathways through different intermediate states produces interference effects on the resonantly enhanced transition probability. This result is supported by the time domain Ramsey interference effect. The two-photon transition spectrum is analyzed in terms of the pulse repetition rate and carrier frequency offset, leading to a cold-atom-based frequency stabilization scheme for both degrees of freedom of the femtosecond laser.
