Abstract
A laser processing apparatus includes an energy distribution correcting unit that forms skirt parts of a Gaussian distribution of an energy distribution in a Y-axis direction regarding a laser beam emitted from a laser oscillator into a perpendicular distribution, an imaging lens group composed of two or more lenses that form an image of the beam shape of the laser beam for which the energy distribution has been corrected by the energy distribution correcting unit on the upper surface of the workpiece, and one cylindrical lens that adjusts the energy density in an X-axis direction regarding the laser beam for which the energy distribution has been corrected by the energy distribution correcting unit.
