Paper Abstract

Based on the signals produced by the induced thermo- electronic current variation, a study regarding the transient processes in laser-solid interaction was developed. Experiments were performed with a Nd:YAG laser, 100 ns pulses duration, by laser beam focusing onto wolfram samples placed into a vacuum chamber. The amplitude and the temporal variation of resulted signals can conclude about the magnitude order of the temperature decay time due to laser-solid interaction. Therefore, the output signal profile analysis gives information about the time evolution of the transient thermal processes determined by the laser radiation absorption.
