Generation of ultraviolet and visible coherent radiation by a four-wave parametric oscillation in barium vapor

Vladimir M. Klimkin, Vladimir G. Sokovikov

Barium vapor emission in the vicinity of the (5d6p1P1COP-6s1S0) and (6p1P1COP-6s1S0) resonance transitions excited by a XeCl* laser has been studied experimentaly. IR radiation ((lambda) equals 2315.8 nm) assigned to the Ba (7p1P1COP-7s1S0) transition has been detected. Four-wave parametric oscillation is assumed to be responsible for the Ba emission. Observations of the interaction range between UV pump radiation and Ba vapor have shown the green emission to be produced from a great number of narrow regions. This effect is attributable either to self- focusing or inversion threads.

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.
