LASER SURFACE WAVE GENERATOR AND GENERATING METHOD FOR LASER SURFACE WAVE OF THE SAME

摘要

A laser surface wave generator according to an embodiment of the present invention includes a laser which emits a laser beam; a laser beam division part which divides a laser beam emitted from the laser into laser beams having the same intensity; laser beam extending members which expand divided laser beams; a linear laser beam conversion member which converts the expanded laser beams into linear laser beams and controls the line width of each of the linear laser beams; and linear laser beam projection position adjusting member which projects each of the linear laser beams to the surface of an object and adjusts the projection position of each of the linear laser beams projected to the object.
