The Overview for the Stability Improvement Strategy of LIBS Spectrum and Analysis Model: From Physics System to Analysis Method.

Laser-induced breakdown spectroscopy (LIBS) technology has been widely used in many fields including industrial production, space exploration, medical analysis, environmental pollution detection, etc. However, the stability problem of LIBS is one of the core problems for its further development. Solutions in the LIBS field in recent decades were summarized and classified from the physical mechanism and analysis method.
