Ultraviolet excitation and stimulated emission in cryogenic rare-gas halide solutions
Abstract
Cryogenic rare-gas halide solutions, excited optically with radiation at 351, 248 and 193 nm, exhibit fluorescence bands corresponding to rare-gas halide dimer and trimer species. For liquid Ar, Kr, and Xe hosts, these emissions display a systematic trend of wavelength shifts and state lifetimes. Due to their strong dipolar character, these excimers radiate in the liquid at wavelengths which are considerably red shifted1 with respect to the gas phase values, interaction. In the case of XeF* , stimulated emission has been observed on the B1/2→X1/2 transition at 404 nm. Energies of ∼110 μJ have been measured in 5 nsec pulses.
