While femtosecond nonlinear Raman techniques typically deal with packets of vibrational quantum states in molecular systems, the technique proposed and implemented in this work uses the results of spectroscopic measurements to reconstruct the temporal structure of short‐pulse wavepackets undergoing continuous frequency downshifting owing to the Raman effect in special optical fibers. Our numerical simulations and experimental results demonstrate that the temporal structure and time dynamics of solitons in photonic‐crystal fibers can be conveniently reconstructed from spectral measurements performed at the output of the fiber.
