| Abstract: | Laser-induced molecular absorptions are reported for the species SF6, CF3I, and CF3Br. Induced absorptions are observed at frequencies ～ 40 cm-1 lower than that of a CO2 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. |
