LASER INDUCED ENERGY TRANSFER PROCESS IN Ba-Yb

Abstract

The collisional interaction between Ba and Yb is not pure dipole-dipole. The maximum of transfer cross section appears at the induced laser wavelength, which corresponds to the interatomic transition. The effect of spin interaction is observed.

Stimulated-absorption and spontaneous-emission studies of laser-induced dipole-quadrupole collisions

J. C. White

Observations are made of dipole-quadrupole laser-induced inelastic collisions occurring during the collision of two Ba atoms. Results for both stimulated-absorption and spontaneous-emission experiments using the same collisional configuration are reported for the first time. In both experiments the interaction maximizes at the $R=\ensuremath{\infty}$ wavelength and has a full-width-at-half-maximum linewidth of \ensuremath{\sim}8 ${\mathrm{cm}}^{\ensuremath{-}1}$. These results bear on the study of the interatomic potentials for colliding atoms and permit the collisional energy transfer to states hitherto inaccessible to dipole-dipole collisions.

LASER INDUCED COLLISIONAL ENERGY TRANSFER : HIGH RESOLUTION STUDIES AND COHERENCE EFFECTS IN DIPOLE-DIPOLE INTERACTION

Catherine Bréchignac, Ph. Cahuzac, Anne Débarre

Two complementary methods have been used to investigate light induced collisional energy transfers for a dipole-dipole interaction. A high resolution spectral profile study in a Na-Ca mixture has confirmed the assumption of a universal profile for a given interaction, the measurement of polarization ratios in a Eu-Sr mixture has confirmed the assumption that such processes may partially preserve the coherences induced by an external polarized field.

Numerical calculation of laser-induced collisional energy transfer in Ba-Sr system

Hongying Zhang, Deying Chen, Zhenzhong Lu +2 more

Based on the existing four-level model of laser-induced collisional energy transfer, the collision process in Ba-Sr system in both weak and strong fields is calculated by immediate integration of the equation of motion, and profiles of laser-induced transition probability and collision cross section under both conditions are obtained. Numerical results for the weak field are in fair to good agreement with former analytical results, while the ones for the strong field show that the effect of laser-induced collision is enhanced when the transfer laser intensity increases. Moreover, the peak of the laser-induced collisional energy transfer spectrum shows an evident shift from resonant frequency to the violet side in strong field, and full width at half maximum (i.e. tuning range) of the spectrum becomes obviously narrower compared with that in weak field.

Cross sections of laser-induced collisional processes: Excitation transfer and charge transfer

S. Geltman

The standard theory for laser- (or light-) induced collisional processes is applied to excitation transfer and charge transfer. Detailed calculations are carried out for specific processes which have been studied experimentally, with good understanding resulting for most of the observed features. We study the variation in cross-section magnitude and line shape with transfer laser intensity, and find characteristic differences between the excitation-transfer and charge-transfer processes.

Laser-induced energy transfer and radiative collisions

P. L. Knight

A theory of the dynamics of radiative collisions is presented in which the laser-induced energy transfer is described by a dipole-dipole interaction between non-identical atoms compounded with stimulated absorption to a further excited level of the acceptor during the collisional interaction.

Observation of laser-induced inelastic collisions

R. W. Falcone, William R. Green, J. C. White +2 more

We describe two new experiments which demonstrate laser-induced inelastic collisions. Energy was stored in the Sr $5p^{1}P^{o}$ state and selectively transferred both to the Ca $4{p}^{2}^{1}S$ and $5d^{1}D$ states. The collision cross sections maximized at the interatomic wavelengths of 4977 and 4711 \AA{}, respectively, and had a half-power width of about 14 ${\mathrm{cm}}^{\ensuremath{-}1}$.
