Measurement of hyperfine structures and isotope shifts of the thallium 6/sup 2/P/sub 1/2/-7/sup 2/D/sub 3/2,5/2/ levels by using the saturated and linear absorption spectroscopy with velocity selective optical pumping

Kwang-Hoon Ko, Sang Eon Park, Do-Young Jeong +4 more

The linear and saturated absorption spectroscopy was performed for the 6/sup 2/P/sub 1/2/-7/sup 2/D/sub 3/2,5/2/ transition lines of /sup 203,205/Tl isotopes. The dependences of the cross-over and the isotope signals in saturated absorption spectra were measured and analyzed on the optical pumping power. The hyperfine splittings and isotope shifts of the 7/sup 2/D/sub 3/2,5/2/ levels of Tl atoms were also measured.

Comparative Measurement of Transverse Nuclear Magnetization of Polarized 129 Xe and 131 Xe by Spin-exch ange Optical Pumping

Yu. Ye Jin, Seong Ho Min, Han-Seb Moon

We analyze the transverse nuclear magnetizations of 129Xe and 131Xe in a vapor cell containing natural Xe, 87Rb, and buffer gases. The Xe atoms are polarized through spin-exchange optical pumping (SEOP) with Rb atoms under low-magnetic-field conditions. From the free-induction-decay (FID) signal, we measure the nuclear magnetization of the Xe atoms in the Xe-Rb vapor cell. Furthermore, we measure the dependence of the gyromagnetic ratio on the magnetization of 129Xe and 131Xe by examining the amplitude of the FID signal of each isotope, and we evaluate the relationship between the magnetic field gradient and transverse relaxation rate for both of the 129Xe and 131Xe isotopes.We analyze the transverse nuclear magnetizations of 129Xe and 131Xe in a vapor cell containing natural Xe, 87Rb, and buffer gases.

One-dimensional laser cooling of an atomic beam in a sealed vapor cell

Chris J. Vale, M. R. Walkiewicz, Peter M. Farrell +1 more

We describe a simple experiment that demonstrates one-dimensional laser cooling in a sealed vapor cell. A velocity selective optical pumping scheme was first used to define a collimated beam of atoms within the cell. A particular velocity group of atoms was labeled by optical pumping with one laser and detected by absorption with a second laser. Transverse cooling of this velocity group, which formed an atomic beam between the two laser beams, was then observed by applying a third laser beam, in analogy with transverse cooling of a conventional atomic beam.We describe a simple experiment that demonstrates one-dimensional laser cooling in a sealed vapor cell.
