The simulation is based on a set of two-dimensional transient equation
s of gas dynamics with two-dimensional radiation transfer equation com
pleted by heat transfer equation for condensed phase. The influence of
the laser radiation wavelength and the choice of the diameter of the
initial high-temperature region in the gas phase (i.e. the region of o
ptical breakdown) on the laser plasma dynamics and the transfer of the
laser and plasma radiation energy to the target are analyzed.
