After almost fifteen years of intense fundamental graphene research it is generally accepted that graphene’s superior physical properties are currently well understood. Major experimental challenges are now related to the large-scale production of high-quality graphene, which is the prerequisite to evolve fundamental graphene science into technological applications. The full potential of laser-assisted methods in graphene production has not yet been unlocked, despite that these methods offer a number of advantages as they are fast, low-cost, environmentally friendly and adaptable to current technological platforms. Few investigations have appeared so far aimed at producing graphene using laser beams, while much more systematic approaches have been undertaken for processing of graphene oxide towards obtaining reduced graphene oxide. Laser wavelengths ranging from ultraviolet to infrared have been used both in the cw and pulsed modes. In their vast majority, studies of laser-assisted methods result in graphene of dubious quality. In this presentation, we will review the current status of the potential of lasers in graphene synthesis and processing and discuss recent and ongoing advances in our laboratory concerning large-scale laser-assisted production of graphene and graphene-based structures.
