Stimulated Raman scattering in a laser-produced plasma heated by laser at wavelength of 0.53 /spl mu/m

摘要

Stimulated Raman scattering (SRS) has been studied in a plasma produced by a second harmonic Nd-glass laser irradiating a limited mass target, which does not burn through during the interaction time. It is assumed that flat density regions form and move through an expanding plasma, and the SRS results have been analyzed on that basis. The SRS spectrum cut-offs are discussed, as well as features of time-integrated and time-resolved SRS spectra.
