<p>The laser beam processing method according to the present invention is a laser beam processing method that performs shape processing on a work to a designated depth position using a laser beam, and is characterized in that the laser power of the laser beam and the relative moving speed between the work and the laser beam are made to be large, and the number of times of irradiation that is necessary for laser beam processing is made to be small so that the energy per unit length of the laser beam that is optimally set depending on the work is within an energy range that does not allow the work to be pierced even when the laser power increases due to a power fluctuation in the laser beam oscillator.</p> |
