Abstract :
Irradiation of intense and ultrashort laser pulses on dielectric surface is calculated in real-time using first-principles time-dependent density functional theory. It is found that calculated energy distribution transferred from laser pulse to electrons in dielectrics explains measured threshold and depth of laser-induced damage.
