Transient molecular absorptions induced by the absorption of CO 2 laser radiation
Abstract
Laser-induced molecular absorptions are reported for the species SF 6, CF 3I, and CF 3Br. Induced absorptions are observed at frequencies ∼ 40 cm -1 lower than that of a CO 2 TEA laser which is used to vibrationally excite the molecules in a low pressure cell. The dependence of the effect on pump laser intensity indicates that the species that exhibit the induced absorption have absorbed more than one laser photon. Applications of this phenomenon with respect to laser induced isotope separation are discussed.
