Stimulated Raman Scattering in KXe

Stimulated Raman scattering has been observed in the transient molecule KXe through the optical excitation of ground state K-Xe pairs. In the wavelength range of 769.6-770.6 nm, 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 state . Additional wavelengths can also be generated through stimulated emission by detuning the pump wavelength as much as 25 cm^-1 from the resonance line, a phenomenom not observed previously in other alkali rare gas systems.
