Description
Summary:•ns and fs Single Pulse Laser Induced Breakdown Spectroscopy (SP-LIBS) has been used for the depth profiling of a bronze sample.•The best results have been obtained by using a fs laser.•The different performances of the ns and fs lasers depend on the different laser–matter interaction mechanisms. Single Pulse Laser Induced Breakdown Spectroscopy (SP-LIBS), performed by nanosecond and femtosecond laser sources has been applied to the study of the depth profiling of the artificially obtained patina of a bronze sample. The results show improved performances of femtosecond LIBS compared to nanosecond one. The differences found in the analyses are related to the different laser–matter interaction processes induced by the different time duration of the laser pulses.
