What we believe to be a new optical approach for the identification of mines and explosives by analyzing the surface materials and not only bulk is developed. A conventional manually operated mine prodder is upgraded by laser-induced breakdown spectroscopy (LIBS). In situ and real-time information of materials that are in front of the prodder are obtained during the demining process in order to optimize the security aspects and the speed of demining. A microchip laser is used as a seed laser for an ytterbium-fiber amplifier to generate high-power laser pulses at with pulse powers up to , a repetition rate of and a pulse duration of . The recorded LIBS signals are analyzed by applying neural networks for the data analysis.
