The nonlinear interaction of counterpropagating waves from two YAG lasers in a single-mode optical fiber has been studied experimentally. The first Stokes component (Я = 1Λ2μπ\) of the signal laser is amplified by a factor of more than 50 as a result of the interaction. Along the time scale, the signal wave is split into peaks less than 5 ps wide.
