Abstract
The vectorial and nonparaxial effects of femtosecond laser pulse propagation in gaseous medium are studied by using an order-of-magnitude analysis. A new vector model equation is established, which is valid for an arbitrarily short laser pulse and includes the effects of the coupling between the transverse and the longitudinal components of the electric field in the created plasma channel, e.g., an electrostatic field created longitudinally by the radiation pressure force and/or the ponderomotive force. In addition, we derive an equation governing the time evolution of the plasma current density, which can be used to analyze the mechanism of energy loss during the propagation.
