We propose an excitation-probe measurement method utilizing entangled photon pulses.

The excitation-probe signal is dominated by nonlinear processes including stimulated Raman scattering.

We demonstrate that the stimulated Raman scattering signal can be relatively enhanced by the entangled photons.

The stimulated Raman scattering signal si composed of many peaks distributed over broad photon energies.

Only the desired peaks among those many peaks can be selected by controlling the thickness of the nonlinear crystal.
