Abstract

A laser system capable of adjusting the shape of a laser beam, according to one embodiment of the present invention, preferably comprises: an image processing unit for processing an image signal inputted from the outside into an RGB signal in a digital format, synthesizing the processed RGB signal, and outputting the synthesized RGB signal as a laser signal; at least one laser beam generating unit for emitting a laser beam according to the RGB signal extracted by the image processing unit; at least one galvo mirror unit for adjusting the scanning direction of the laser beam so that the laser beam is reflected toward the air or screen at a specific position; and at least one laser beam shape adjusting unit, positioned between the laser beam generating unit and the galvo mirror unit, for adjusting the shape or size of the laser beam by predetermined information while the laser beam emitted from the laser beam generating unit is transmitted along a laser beam path.
