Abstract

Stimulated Raman scattering in the transient limit in which pulse durations are short compared to the material de-excitation time T₂ (TSRS) has long been the focus of theoretical and experimental study. Recent experiments¹ have observed pump depletion and amplitude oscillation, Second-Stokes generation imposed an upper limit on the length of these experiments, but it has since been found experimentally that it is possible to use a multiple-pass geometry to suppress this generation,² allowing one, in principle, to observe TSRS over very long lengths. The equations that describe stimulated Raman scattering in H₂ and other gases may be written after normalization as
