In this paper, effect of the magnitude and the sign of frequency chirp of femtosecond laser pulses focused inside both media of isotropic silica glass and anisotropic Lithium Niobate crystal on plasma density distribution generated in the vicinity of focus are numerically studied. The simulations reveal that these two media have different behavior for the same sign of chirp of incident pulse. Moreover, frequency chirp of the incident pulses is an appropriate parameter for controlling of the plasma distribution at the vicinity of focus in the applications of waveguide writing based on femtosecond lasers.
