Quantum calculations for spin-changing collisions in Ba [(6s6p),3P 2 ←1P 1 ] +Ne inelastic transition

E. Paul-Kwiek, A. Pietka, E. Wozniak

The quantum close-coupling studies of the 3P2<-1P1 spin changing transitions in Ba (6s6p) colliding with Ne involving changes of magnetic quantum numbers are presented. The differential and multi-structure cross-section are calculated in a range of relative translational energies from threshold to 0.4 eV. The results of calculations exhibit the Stuckelberg oscillations and strong backward scattering effects.

Pair-absorption-pumped barium laser

R. W. Falcone, G. Zdasiuk

This is the first reported demonstration of the use of pair-absorption transitions for optically pumping lasers. In a mixture of barium and thallium metal vapors, single-photon absorption of 3867-A laser light caused simultaneous excitation of colliding ground-state atoms to the Ba(6s6p 1P1(o)) and Tl(6p 2P(3/2)(o)) excited states. Excited-state densities of about 10(14) cm(-3) were created, and subsequent laser emission on the Ba(6s6p 1PI(o)) - Ba(6s5d 1D2) atomic transition at 1.5 microm was observed.This is the first reported demonstration of the use of pair-absorption transitions for optically pumping lasers.
