Abstract: A laser processing machine includes: a laser oscillator which emits laser light; a scanning unit which scans a processing target surface of a work by deflecting the laser light emitted from the laser oscillator; and a focusing unit which is disposed between the laser oscillator and the scanning unit and which focuses the laser light emitted from the laser oscillator. The focusing unit is set so as to focus the laser light at a second position that is more distant from a first position where the laser light is incident vertically than a third position that is farthest from the first position in the processing target surface of the work.

Abstract: A laser processing apparatus comprises a first shift mechanism including a first transparent member having a first incident face and a first output face that are parallel to each other; and a first motor that rotates the first transparent member around a first rotational axis. The first shift mechanism shifts the laser beam exiting from the first output face in a state parallel with the incident light on the first incident face in a first direction. The laser processing apparatus also comprises a second shift mechanism including a second transparent member including a second incident face and a second output face that are parallel to each other; and a second motor that rotates the second transparent member around the second rotational axis. The second rotating mechanism rotates the laser beam exiting from the second output face in a state parallel with the laser beam incident on the second incident face in a second direction perpendicular to the first direction.
