Abstract
A laser processing system and a laser processing method that can highly accurately and efficiently specify a focus position of a processing laser using visible lasers are provided. For that purpose, a laser processing system includes a processing laser oscillator, a condensing optical system including a condenser lens, two visible laser oscillators and, a movement adjusting unit that adjusts the condenser lens and the visible laser oscillators and to move forward and backward in synchronization with each other, an imaging unit that images spot lights of the visible lasers on a workpiece, an image processing unit that subjects an imaged video to image processing and displays an image after the processing, a calculating unit that calculates, in a state in which the respective visible lasers are focused on a focus position of the processing laser, center of gravity positions of spot lights of the respective visible lasers formed on the surface of the workpiece according to the movement of the condenser lens and calculates a distance between centers of gravity, and a control unit that controls the movement adjusting unit such that the distance between centers of gravity is adjusted to zero or substantially zero.
