Abstract
Theoretical and experimental investigations were made of the transient amplification of the Stokes component beams in hydrogen. The use of t he pump and seed Stokes beams with deliberately matched spatial profil es makes it possible to increase the energy efficiency of the conversi on to the Stokes component, compared with the efficiency when the inte racting beams have similar, but not completely matched profiles. Mecha nisms limiting the efficiency of amplification of the Stokes component are discussed.
