摘要: The birefringence of a linearly polarized femtosecond laser filament in gases has been previously established. In this work, we report the time-dependent refractive index measurements based upon spectral modulation weak probe pulse air and argon gas at 1 atmospheric pressure. polarization dependence induced by delayed molecular alignment electronic Kerr effect is highlighted. A numerical simulation indices, which takes into account alignment, non-linearity plasma, good agreement with measurements.
