Gain reduction measurements in transient stimulated Raman scattering

Threshold energy measurements of transient rotational stimulated Raman scattering are compared to Raman conversion calculations from semiclassical theories using a simple concept of a gain reduction factor which expresses the reduction of the gain from its steady-state value due to transient scatter...

Description
Summary:Threshold energy measurements of transient rotational stimulated Raman scattering are compared to Raman conversion calculations from semiclassical theories using a simple concept of a gain reduction factor which expresses the reduction of the gain from its steady-state value due to transient scattering. Excellent agreement was found with theoretically derived gain reduction in the transient and highly transient case.< >
