Abstract
The interaction of subpicosecond laser pulses with metals is studied theoretically using phenomenological two-temperature model. A semi-analytical approach to a quantitative analysis of electron and lattice temperatures is presented. Using the nonstationary averaging technique the coupled system of nonlinear heat equations for electron and lattice temperatures is transformed into the set of four ordinary differential equations. Resulting system is convenient for the fast analysis of nonstationary laser heating and laser ablation with ultrashort laser pulses.
