Coherent Laser-Atom Interaction and its Application to Atomic Frequency Offset Locking
نویسنده
چکیده
Electromagnetically Induced Transparency (EIT) refers to the phenomenon of rendering an otherwise opaque medium, transparent to a narrow band of light frequencies. Physics underlying this phenomenon and its use as atomic frequency standard has been discussed extensively in literature. An ultra-narrow linewidth of the EIT signal may be considered as a narrow band frequency filter, since it is associated with a sharp change in dispersion of the medium. It therefore can be used as a frequency reference for offset locking, where the offset is precisely equal to the known energy gap between two atomic levels. In this paper, we describe development and Abstract

Laser frequency offset locking by marrying modulation sideband with the two-color polarization spectroscopy in a ladder-type atomic system
We present an investigation of two-color polarization spectroscopy (TCPS) based on cesium 6S1/2–6P3/2– 7S1/2 (852 nmþ1470 nm) ladder-type system in a room-temperature vapor cell. The 1470 nm laser can be offset locked by TCPS combining with frequency modulation sideband. This locking scheme offers a method of modulation-free and conveniently tunable the lock point of laser frequency relative to...
متن کاملPhase-Coherent Multilevel Two-Photon Transitions in Cold Rb Atoms: Ultrahigh-Resolution Spectroscopy via Frequency-Stabilized Femtosecond Laser
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 Ra...
متن کاملProduction of Multiple Rb Condensates and Atom Lasers by Rf Coupling
One of the major goals in the study of Bose–Einstein condensation (BEC) in dilute atomic gases has been the realization and development of atom lasers. An atom laser may be understood as a source of coherent matter waves. One can extract coherent matter waves from a magnetically trapped Bose condensate. Schemes to couple the atomic beam out of the magnetic trap have been demonstrated [1, 2, 3, ...
متن کاملSoliton Atom Laser with Quantum State Transfer Property
We propose a scheme to obtain soliton atom laser with nonclassical atoms based on quantum state transfer process from light to matter waves in nonlinear case, which may find novel applications in, e.g., an atom interferometer. The dynamics of the atomic gray solitons and the accompanied frequency chirp effect are discussed. PACS numbers: 03.75.-b, 42.50.Gy, 03.65.Ta, 03.67.-a Since the first pu...
متن کاملCoherent control of spontaneous emission near a photonic band edge: A qubit for quantum computation
We demonstrate the coherent control of spontaneous emission for a three-level atom located within a photonic band-gap structure with one resonant frequency near the edge of the photonic band gap. Spontaneous emission from the three-level atom can be totally suppressed or strongly enhanced depending on the relative phase between the steady-state control laser coupling the two upper levels and th...
