LIBS technique is a non‐destructive technique used for elemental analysis. One way of improving the sensitivity of the technique is using femtosecond laser. In the present work, the elemental composition of 50 cent and one Euro coins has been presented, and the quantitative analysis of each element has been obtained adopting the plotted calibration curves for certified bronze alloys. In this experiment, focused KrF laser pulses at (248 nm) have been used to generate plasma. The atomic emission lines are spectrally dispersed using a grating spectrometer and detected with ICCD over an approximately 20 nm range.
