Physical Review A

Doppler-free two-photon absorption of two coherent beams

Ming Chiang Li

Published Dec 1, 1977• 3 citations
Publisher

Abstract

Proposed and performed experiments on the Doppler-free two-photon absorption of two coherent laser beams are discussed. The coherent phenomenon in experiments follows directly from basic quantum mechanics. It is shown that, to excite the coherent absorption, the laser beams need not be spatially or temporally separated.

Resonance fringes in the two-photon absorption with a Doppler shift

Ming Chiang Li

The two-photon absorption initiated by two coherent beams is considered. It is shown that the resonance fringe variation, which appeared in the Doppler-free two-photon absorption of pulsed laser beams, can also be observed in absorption with a Doppler shift.

Three-Photon Doppler-Free Spectroscopy: Experimental Evidence

G. Grynberg, F. Biraben, M. Bassini +1 more

We report here the first experimental demonstration of Doppler-free three-photon spectroscopy. The Doppler broadening is eliminated by insuring that the sum of the momenta of the three photons simultaneously exchanged between the atom and the laser beams is equal to 0. This is accomplished by making a proper choice of the angles between the three exciting beams. The observation has been made on the sodium $3{S}_{\frac{1}{2}}\ensuremath{-}3{P}_{\frac{1}{2}}$ transition with absorption of two photons and induced emission of one.

Second order interference in two photon absorption

M. W. Hamilton, Daniel S. Elliott

Two photon absorption is considered in the context of second order coherence measurements. We examine second order interference fringes for the typical Doppler free spectroscopic layout which involves a retro-reflecting mirror. The fringes are manifested in the wings of the absorption spectrum and their observability requires partial decoherence of the exciting laser light.

Induced two-quantum Doppler-free gamma emission

Nikolay N. Evtikhiev, Задерновский Анатолий Андреевич

Summary form only given. We discuss a way to remove the negative role of chaotic motion of nuclei by ignition of two-quantum induced gamma emission in counterpropagating intense photon beams. Our approach is based on a well known Doppler-free technique used in two-quantum absorption spectroscopy.

Coherence in two-photon down-conversion induced by a laser

L. J. Wang, X. Y. Zou, L. Mandeļ

Normally, the signal and idler photons produced in the process of parametric down- conversion exhibit no second-order interference. However, in the presence of an external laser beam that follows the path of the signal photon and induces stimulated down-conversions, one would expect coherence to develop between the down-converted signal and idler beams. We have demonstrated the existence of this phenomenon in an experiment with two down-converters pumped by similar pump beams, in which two mutually coherent laser beams followed the paths of the two down-converted signal photons and induced coherence between the two down- converted idler beams. The induced coherence gives rise to observable interference effects, which are presented.

Interaction of laser radiation with free atoms

S. Feneuille

The review describes and interprets the basic phenomena recently observed in the interaction between free atoms and laser radiation. Some of these have been known for a long time in magnetic resonance but in the optical range, the situation is strongly modified because of spontaneous emission and the Doppler effect. Therefore, particular attention is paid to resonance fluorescence and Doppler-free spectroscopy but without dwelling on applications. Transient effects are also discussed, but all the phenomena which characterize, not specifically the interaction between atoms and fields, but the free evolution of atoms after coherent excitation are ignored. Pulse propagation experiments are described in detail and multiphoton processes are considered, with special emphasis on Doppler-free multiphoton excitation and resonant multiphoton ionization.
