Abstract:
1. A laser processing device comprising: a chuck table for holding a workpiece; a laser beam irradiating unit for irradiating the workpiece held on said chuck table with a pulsed laser beam, said laser beam irradiating unit including a laser oscillator, and including an irradiation unit for irradiating the workpiece with the pulsed laser beam oscillated by said laser oscillator; a controller for controlling said laser beam irradiating unit; a processing feed unit for moving said chuck table in an X-axis direction, and for outputting X-axis coordinate values of said chuck table; and an indexing feed unit for relatively moving said chuck table and said laser beam irradiating unit in a Y-axis direction, and for outputting Y-axis coordinate values based on a location of said chuck table and said laser beam irradiating unit, wherein said controller includes
