  An analysis is made of the effect of a strong field on the shape of the
amplification spectral line for mono-velocity V-type three-level atoms. There
are three strong-field contributions, differing in their dependence on the set
of relaxation parameters of the medium and on the differences among the
populations corresponding to the Raman transitions. An analysis is made of the
conditions under which each of the contributions is predominant. The change in
the line shape by an intensified external field is found for each case. Neon
atoms are discussed as an example. The results are compared with those
corresponding to a Maxwellian velocity distribution.
