Stimulated electronic Raman scattering as a tunable infra-red source

Abstract

Stimulated electronic Raman scattering in potassium vapour has been used to produce tunable infrared radiation around 2.7 μm. A tuning range of ~1000 cm⁻¹ has been observed with powers up to 1 kW. The Raman output has been used to obtain an absorption spectrum of CO₂ gas with a resolution of better than 0.4 cm⁻¹.
