Real-time automatic recognition of solids using laser-induced breakdown spectroscopy

Real-time automatic recognition by laser-induced breakdown spectroscopy of both bulk and granular materials at distances up to 5 m was performed. As a radiation source diode-side-pumped passively Q-switched Nd:YAG laser with a multiloop self-adaptive reciprocal cavity was used. Also, the possibility of materials recognition by mean of self-Q-switching on plasma mirror was demonstrated.
