Stimulated Raman scattering of KrCl laser radiation in CH 4
Abstract
Stimulated Raman scattering experiments in methane have been performed using an UV-preionized KrCl discharge laser (222 nm) as the pump. The effect of the pumping beam divergence on the photon conversion efficiency has been investigated. Photon conversion efficiencies of 45% to the first Stokes at 237 nm were measured at 35 atm of methane pressure. The results are compared with those obtained in hydrogen as Raman medium under the same experimental conditions.
