Phase Conjugation by Degenerate 4-Wave-Mixing in Barium Vapor (Journal article)

Mikropoulos, T. A./ Cohen, S./ Kompitsas, M./ Goutis, S./ Baharis, C.

We report what is to our knowledge the first observation of phase-conjugate waves by degenerate four-wave mixingin Ba vapor near its 6s2'So - 6s6p 1P, resonance transition. A maximum reflectivity of 36% at 10 mbars of Ar buffer gas pressure is observed together with a temporal pulse shortening of 50%. Conical emission in the two pump waves after their passage through the nonlinear medium is also observed. The dependence of the phase-conjugate signal on the pressure of the Ar buffer gas shows a small state-changing collisional decay rate.
