Nuclear fusion has enormous potential to greatly affect global energy production. The next-generationtokamak ITER, which is aimed at demonstrating the feasibility of energy production from fusion ona commercial scale, is under construction. Wall erosion, material transport, and fuel retention areknown factors that shorten the lifetime of ITER during tokamak operation and give rise to safetyissues. These factors, which must be understood and solved early in the process of fusion reactordesign and development, are among the most important concerns for the community of plasma-wallinteraction researchers. To date, laser techniques are among the most promising methods that cansolve these open ITER issues, and laser-induced breakdown spectroscopy （LIBS） is an ideal candidatefor online monitoring of the walls of current and next-generation （such as ITER） fusion devices. LIBSis a widely used technique for various applications. It has been considered recently as a promising toolfor analyzing plasma-facing components in fusion devices in situ. This article reviews the experimentsthat have been performed by many research groups to assess the feasibility of LIBS for this purpose.
