Molecular Raman in KXe

Stimulated electronic Raman scattering has been observed in the transient molecule, KXe, by optically exciting ground state K-Xe pairs. Stimulated emission with a linewidth of 2 cm^-1 on the B²Σ⁺_1/2→X²Σ⁺_1/2 transition of the molecule has also been observed despite the dissociative nature of the B²Σ⁺_1/2 potential in the interval 769.6‑770.6 nm. Additional wavelengths can be generated through stimulated emission by detuning the pump wavelength away from the resonance line, a phenomena previously not observed in other alkali rare gas systems.
