Measurements of Resonance Imprisonment in D1and D2Lines of Sodium Vapor Using a Spectrally Narrowed Dye Laser

Abstract

The effect of resonance imprisonment on the atomic lifetime which is remarkable in resonance D lines of sodium vapor is largely dependent on the optical thickness of the vapor and on the oscillator strength of the transition. The measurement of resonance imprisonment of sodium D 1 and D 2 lines was made using a N 2 laser-pumped narrow-band dye laser which enables excitation of the D 1 and D 2 lines separately. The measured results were compared with the theories given by Milne and Holstein, each of which shows partial agreement with the results in different vapor pressure regions.

Effect of Imprisonment of Radiation in Sodium Vapor on the Measured Lifetime of the 3 P2 States

B P Kibble, G. H. Copley, L. Krause

The effect of imprisonment of radiation in sodium vapor on the measured lifetime of the $3 ^{2}P$ states has been investigated in an experiment in which the atoms in the vapor were excited with 10-nsec pulses of resonance radiation and the elapsed times between the exciting and the fluorescent pulses were recorded using a time-to-amplitude converter and kicksorter. At vapor densities below ${10}^{10}$ atoms/${\mathrm{cm}}^{3}$, where there is no multiple scattering, the measured lifetime reaches a constant value of (1.63\ifmmode\pm\else\textpm\fi{}0.04)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}8}$ sec, equal to the natural lifetime of the $3 ^{2}P$ states. In the density range ${10}^{9}$-${10}^{13}$ atoms/${\mathrm{cm}}^{3}$, the variation of the effective lifetime with the vapor density is in good agreement with the predictions of Milne's theory of radiation trapping; agreement with Holstein's theory is observed only in the range ${10}^{12}$-${10}^{13}$ atoms/${\mathrm{cm}}^{3}$. The results of a subsidiary Hanle experiment show that a multiply scattered photon of sodium resonance fluorescence loses its original polarization and that, at high sodium vapor pressure, coherence is not preserved.

Observation of resonance radiation pressure on an atomic vapor

John E. Bjorkholm, Arthur Ashkin, D. B. Pearson

We have used the resonance radiation pressure from 40 mW of cw dye laser light propagating axially down a tube filled with sodium vapor to increase the sodium pressure (density) up to 50% over a length of 20 cm. The magnitude of the effect agrees well with measurements of the absorbed power. These observations were made with the laser tuned to the low-frequency side of the sodium D2 resonance line; for tuning to the high-frequency side, an additional unexplained effect leading to density decreases was observed.

The Imprisonment and Quenching of Sodium and Potassium Resonance Radiation.

The met h o d of delayed coincidences for measu r i n g lifetimes of excited states has been used to investigate imprisonment of radiation in potassium vapor and to measure quenching cross sections in mixtures of potassium w ith diatomic gases and sodium wi t h noble gases.The me thod has also been u s e d to investigate the possibility that a longlived molec u l a r complex might be formed in inelastic collisions between 2 potassium and xenon, which lead to excitation transfer between the P potassium states.The alkali metal atoms were excited w i t h short pulses of resonance radiation, and the delays between the exciting and fluores cent pulses were m e a s u r e d w i t h a time-to-amplitude converter.At 10 3 pure potassium densities below 10 atoms/cm , the m e a s u r e d lifetimes approach the constant values of 27.8 + 0 .8 and 27.6 + 0 .8 nsec, 2 2 corresponding to the m e a n lifetimes of the 4 ^^2 anc* ^ ^3 / 2 s t a t e s > respectively.At higher densities, the apparent lifetimes are in satisfactory agreement w i t h the predictions of H o l s t e i n 's theory.The decrease in the apparent lifetimes, u p o n addition of diatomic gases to the potassium vapor, yielded cross sections for quenching collisions w it h N^, H^, HD and D^, which equal 34.0 + 2 .0 X2, 9.4 + 1.3 X2, 11.9 + 1.5 X2 and 8 .0 + 2 .0 X2, respectively.Addition of the noble gases He, Ne, Kr, Ar and Xe to sodium vapor did not lead to any measurable change in the decay rates for the sodium states within the iii

Time-Resolved Spectroscopy With A Narrow-Band Pulsed Dye Laser At High Irradiances

We measured the fluorescence spectrum of the Na-D lines in a sodium vapour cell filled with Ar gas, excited by an intense, nearly monochromatic laser near resonance. In this case the theory (dressed-atom model) predicts a line splitting dependent on the laser intensity.

This paper considers the issue how to obtain the amplification of stimulated emission in the cell with sodium vapor using a longitudinally pumped dye laser arrangement at a line shorter than the transitions from the ground state to the levels D1and D2. The broadening of the emission wavelength is calculated.

Line polarization of laser-excited Na D2 -transition resonance fluorescence

X-K. Meng, W. R. MacGillivray, M. C. Standage

The sodium ${\mathit{D}}_{2}$ transition is resonantly excited by \ensuremath{\pi}-polarized, narrow-band laser radiation. The line polarization of the resulting fluorescence detected normally to the plane containing the electric-field vector of the radiation and its propagation direction, as well as the atomic beam, is measured as a function of radiation intensity and tuning. The data are compared to calculations from a quantum-electrodynamic theory which includes all participating energy states in the hyperfine representation. The quantitative agreement is very good.
