Abstract	Cathodoluminescence is a characteristic photon emission in the visible light range of an electromagnetic spectrum caused by the interaction between high-energy electron bombardment and solid. Its implication for the Geosciences has already been described by previous studies, but the application to the Laboratory Astrophysics has not been debated in details, up to date. This overview talk is to provide a summary of the preliminary examinations of the cathodoluminescence investigations (as potentials of this technique) in the laboratory analogous materials providing some important information about the possible formation mechanism of forsterite in the Early Solar System and diamonds in the planetary nebula as well as determination of shock wave history of the fine-grained astromaterials, respectively.
