Stimulated Raman Scattering in a Calcite Single Crystal at Picosecond Laser Excitation

Abstract

Spectra of multiparticle parametric stimulated Raman scattering in a calcite single crystal are investigated. The single crystal is excited by ultrashort pulses of the Nd3+:YAG laser with the lasing wavelengths of 532 and 1064 nm. A comb of Stokes and anti-Stokes components is observed in the visible and near infrared regions. Energy dependences are constructed for several Stokes and anti-Stokes satellites. A possibility of collinear propagation of Stokes and anti-Stokes components in forward scattering is found.
