Abstract
A laser processing apparatus includes a laser beam applying unit for applying a laser beam to a workpiece, an image capturing unit for producing a captured image of the workpiece that includes a captured image of light emitted from the workpiece when the laser beam is applied to the workpiece by the laser beam applying unit, and a control unit. The laser beam applying unit includes a laser oscillator for emitting a laser beam and a condensing lens for converging the laser beam onto the workpiece. The control unit includes a determining section for determining a state of the laser beam applied to the workpiece, on the basis of the shape of the captured image of the light that is included in the captured image of the workpiece.
