Competition of Stimulated Raman Scattering in H2-CH4 Mixed Gases
-
Abstract
Competition of stimulated Raman scattering was observed in hydrogen-methane mixed gases pumped by a KrF laser. The Stokes pulse of methane gas oscillated, shortened and was destroyed with the addition of various ratios of hydrogen gas. A model including the feedback of the cell windows as well as competition between hydrogen and methane gas agree well with the experimental observations. -
