Measurements of polarization of filamenting light pulses at 800 nm are presented. Electronic nonlinearity, molecular alignment and nonlinear losses all contribute to modify the polarization of a femtosecond filamenting pulse. The polarization is modified in each stage of preparation, filamentation and divergence after the filament.
