Phys. Rev. Lett. 84, 5508–5511 (2000)fs-Pulse Synthesis Using Phase Modulation by Impulsively Excited Molecular VibrationsReceived 26 January 2000; published in the issue dated 12 June 2000 We report the temporal characteristics of laser radiation transmitted through impulsively excited SF6 and exhibiting sideband Raman lines. Even without special dispersion control we observed a sequence of compressed fs pulses following with the period of the excited A1g vibrational mode of SF6. The use of both negative and positive group velocity dispersion compensation for the temporal compression was found to be as appropriately efficient. The results prove our new concept of the ultrafast molecular phase modulator. © 2000 The American Physical Society URL:
