An apparatus for preparing graphene by means of laser irradiation in liquid, comprising a laser generating system, and further comprising a computer control system, a cleaning and drying system, and a workpiece auxiliary system. The light spot diameter of the laser emitted from a pulse laser unit () is increased by means of a beam expander (), and the laser is reflected and split by a beam splitter to form two laser beams; a first laser beam () shocks the right vertical plane of a graphite solid target () by means of a focusing lens, and a second laser beam () shocks the left vertical plane of the graphite solid target () by means of the focusing lens, so as to grow graphene on a copper foil () substrate.
