Abstract
Stimulated Raman scattering in the stationary limit is considered in a crossing-pump-beam geometry. The effect of spatial phase aberrations that broaden the spread of the transverse wave numbers is studied. It is found that beam replication is due predominantly to excess gain induced by the pump scintillations rather than to nonlocal four-wave mixing.
