Abstract : A model has been developed for the propagation of a femtosecond laser pulse through an ionizing medium, which predicts the spectral shift and broadening in the transmitted pulse, and the electron energy distribution within the plasma. For gaseous targets at laser intensities of 10 to the 15th010 to the 16th W/sq. cm., the calculated blue-shifts do not agree with predictions from a homogeneous Drude model. The importance of the electron energy distribution for cold-plasma production in solid-target experiments is discussed.
