Cover Story: Portable laser-induced plasma spectroscopy (LIPS) is recognized as a powerful tool for addressing a large variety of elemental composition problems in situ. However, the application of the most sensitive configuration of this technique, which is based on double-pulse laser excitation (DP-LIPS), still remains confined to complex laboratory setups. Here, we demonstrated the possibility to achieve significant signal intensification and reliable quantification using a high-energy passively Q-switched Nd:YAG laser, which can emit pulses with multiple power peaks spaced at several tens of microseconds. Such an excitation source can allow compacting and reducing the costs of DP-LIPS instruments. The validation of this novel system developed was successfully carried out by investigating the alloy compositions of a bronze statuette from the Egyptian Museum of Florence. View this paper.
