Sideband generation using strongly driven Raman coherence in solid hydrogen

Parametric Raman sideband generation is investigated using strongly driven Raman coherence in solid hydrogen. We show that the Raman coherence prepare d with two coaxial single-mode lasers beats with multimode laser radiation with very broad bandwidth and efficiently replicates the broadband nature t o the Raman sidebands without the restriction of phase matching. We demonst rate that this efficient replication occurs mainly on the negative side of Raman detuning, where the medium adiabatically follows the antiphased state .
