Abstract

An experimental measurement by using Laser Induced Breakdown Spectroscopy (LIBS) and Photoacoustic Induced by Laser Ablation (PILA), in order to monitoring the microcraks formation inside the glass induced by laser pulses is presented in this work. The laser was operated in both single pulse and multi-pulse Q:Switched regime using a passive Cr:YAG crystal as switching element. The LIBS spectra captured inside the glass avoid identifying the sample composition without influence of surrounding atmosphere like occurs if the spectra are obtained on the surface. On the other hand, the PILA signal permits to monitor the process and its dependence from the number and intensity of micro-pulses.
