Title: Depolarization of femtosecond pulses in air by nonlinear mechanisms
Keywords: Depolarization, Cubic type nonlinearity, Ultara-short laser pulses

Abstract: In recent experiments in air with femtosecond pulses significant depolarization effects in nonlinear regime were observed. We use the generalized cubic type nonlinearity and investigate how this operator influences the vector field polarization. A vector set of nonlinear differential equations describing the evolution of the main and signal is derived. The polarization properties of the components of vector fields are investigated numerically.
