A technique for complete population transfer between the two end states |1\ensuremath⟩ and |3\ensuremath⟩ of a three-state quantum system with a train of N pairs of resonant and coincident pump and Stokes pulses is introduced. A simple analytic formula is derived for the ratios of the pulse amplitudes in each pair for which the maximum transient population P2(t) of the middle state |2\ensuremath⟩ is minimized, P2max=sin2(\ensuremathπ/4N). It is remarkable that, even though the pulses are on exact resonance, P2(t) is damped to negligibly small values even for a small number of pulse pairs. The population dynamics resembles generalized \ensuremathπ pulses for small N and stimulated Raman adiabatic passage for large N and therefore this technique can be viewed as a bridge between these well-known techniques.
