In recent years, therefore, the potential application of porous graphene in the fields of biology, materials, energy sources, information and the like and the preparation technology thereof are receiving a great deal of attention. Porous graphene can be fabricated in situ on a substrate surface by chemical vapor deposition and plasma enhanced chemical vapor deposition. However, the high temperature conditions required for the process either limit the substrate type or impair the mechanical properties of the substrate.

However, the existing laser generating device cannot directly act on the induction production of graphene, and the existing laser generating device lacks corresponding production equipment, and the existing single-point laser irradiation has poor continuity, so that a graphene laser induction scanning device suitable for LIG technology application is needed.
