​Laser Induced Breakdown Spectroscopy (LIBS)

LIBS has a similar objective as the APXS — to detect the abundance and types of elements located close to the landing site. The main difference is that instead of using X-Rays, LIBS fires out high-powered laser pulses and analyses the resulting radiation caused by the decay of plasma.
