ABSTRACT:
An ablation apparatus for ablating only a convex part on a rough surface efficiently in a short time, providing a light delivering optical system for delivering a laser beam being a slender from a laser beam source rectangular shape to an object to be ablated, a beam moving device for moving the laser beam to an intersecting direction relative to the optical axis of the light delivering optical system, a dividing-and-masking device for dividing selectively a longer-side direction of the laser beam of which a cross section is a rectangular shape and masking the same selectively, a data input device for inputting data relating to an ablation area of the object, and a control device for controlling the condition masked by the dividing-and-masking device at respective positions of the laser beam moved by the beam moving device based on the data inputted by using the data input device, wherein convex parts of the object of which a surface being roughness is ablated by the laser beam through the dividing-and-masking device and the beam moving device.
