摘要：

We report on the observation of a Raman frequency conversion mechanism different from the usual Stokes (anti-Stokes) stimulated process. A continuous down-shift of laser pulse frequency was measured for sufficiently short (less than or equal to 40 fs) pulses propagating in gaseous SF6. We attribute this behavior to the extremely nonstationary nuclear response of SF6 molecules to the light field with a duration shorter than the period of the Raman-active vibration.
