Since 1980s, Laser-Induced Breakdown Spectroscopy (LIBS) has been
developed, (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic
laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes
and excites samples. The formation of the plasma only begins when the focused laser
achieves a certain threshold for optical breakdown, which generally depends on the
environment and the target material. The versatility of (LIBS) has been demonstrated in
various industrial application. Laser-induced breakdown spectroscopy will be discussed in
this article including its fundamentals, industrial applications, and challenges.
