Abstract

Coherent propagation of resonant ultrashort pulses in gases is investigated theoretically and experimentally at medium pressure values. Drastic changes of the pulse wings extending over several ten picoseconds are predicted and experimentally observed using tunable pulses of 4 ps produced by a parametric generator device and picosecond IR light gates. The dephasing time T₂ of the R(3) vibration-rotation transition of HCl is measured to be T₂ × p = 21.5 ps × bar in the pressure range p = 1 to 3 bar. Quantitative agreement between theory and experiment demonstrates that a novel transient spectroscopy in the infrared can be accomplished by coherent pulse reshaping.
