Abstract

A laser transfer printing device and a laser transfer printing method are provided. The laser transfer printing device includes a laser, a beam expander, a beam splitter and a focusing module. The laser is configured to generate a laser beam. The beam expander is disposed on an optical path of the laser beam generated by the laser to expand the laser beam generated by the laser. The beam splitter is disposed on an optical path of the laser beam expanded by the beam expander to reflect the expanded laser beam to the focusing module. The focusing module is disposed on an optical path of the laser beam reflected by the beam splitter to focus the laser beam and project the focused laser beam to a predetermined transfer processing position.
