We study theoretically a pulse compression method with gas-filled hollow-core fiber based on ultrafast molecular phase modulation. The simulation results show the molecular phase modulation can impart a positive or negative chirp on probe pulse and tune the central wavelength by changing the time delay between the pump and probe pulses. This approach is demonstrated to be suitable for generation of frequency-tunable few-cycle pulses with a smooth spectrum.
