From rocks on Mars to fields on Earth, LIBS is helping scientists do their jobs with improved speed, safety, and precision.

Laser-induced breakdown spectroscopy (LIBS) is a technique that reveals the presence and concentration of elements in a sample. Pioneered and perfected at Los Alamos, LIBS is virtually non-destructive, portable, adaptable, rapid, remote, and affordable—making it handy for a broad variety of applications. From improving energy- and food-security on Earth to exploring Mars and maybe someday Venus, LIBS is definitely doing big things in science.
