Raman and UVN+LWIR LIBS detection system for in-situ surface chemical identification

Laser Induced Breakdown Spectroscopy (LIBS) in the Ultra Violet/Visible/Near-IR (UVN) spectral range is a powerful analytical tool that facilitates the interpretation of Raman spectroscopic data by providing additional details in elemental chemistry. To acquire the complete information of molecular vibrations for more accurate and precise chemical bonding and structural analysis, an ideal in situ • A single excitation laser pulse is used to trigger both UVN and LWIR spectrometers simultaneously. • Time-resolved UVN-LWIR LIBS measurements showed the evolution of both atomic and molecular signature emissions of target compounds in the laser-induced plasma. • The technique was applied to the characterization of mineral and organic compounds in planetary analog samples.
