Theoretical studies have been performed on the interaction of short
laser pulse with metals. The results of the theoretical model indicate
that heat conduction would not be uniform from focal spot or crater at the
surface of target metal, when an ultra short laser will interact with the
metal. The electromagnetic radiations of laser induce electric field
inside the target that is responsible for the induction of current
density, which causes electronic heat conduction in the direction of
current density. Such an effect is dominant for laser pulse having
duration less than of the order of sub-picoseconds. This mode will open a
new significant field of study to discuss laser metal interaction for
ultra short laser pulses.
