Stimulated Raman scattering in lead vapor pumped by a long‐pulse 1‐J XeCl excimer laser

摘要

The parametric dependence of the output energies and efficiencies for the Raman conversion of the radiation from a long‐pulse 1‐J XeCl excimer laser in Pb vapor was investigated. The effects of atom depletion and buffer gas on the stimulated Raman scattering output were discussed in detail. Multipeak structures of the waves of the Raman‐shifted pulses were observed which could be attributed to the coherent effects in Raman scattering. A computer model was introduced to explain the multipeak structures of the stimulated Raman scattering waveforms.
