摘要: Laser-Induced Breakdown Spectroscopy (LIBS) and Raman spectroscopy are complimentary techniques. LIBS yields elemental information while molecular about a sample, both share similar instrumentation configurations. The combination of in single instrument for planetary surface exploration has been proposed, however challenges exist developing combined instrument. We present results obtained using diode pumped, intracavity doubled, Q-switched, Nd:YLF laser operating at 523 nm, which overcomes some the difficulties associated with spectra were 170 μJ per pulse 4 Hz repetition rate low pressure Mars-simulated atmosphere produced 200 mW 100 kHz. is switchable between modes only by change Q-switch rate. Emissions from Ca, Ca II, Fe, Fe Mg, Na, O atom identified μ-LIBS spectrum oolithic hematite. Evidence was found plasma dynamics 7 5 Torr that could be explained as decrease temperature electron density below Torr. This relevant to future Mars mean on varies 3.75 6 should carefully evaluated pressures will encountered specific landing site.
