20100288740 | LASER PROCESSING APPARATUS AND LASER PROCESSING METHOD - 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. A light collecting lens collects the laser beam shifted with the second shift section to process a work. This configuration allows control of a taper angle of a hole formed by laser processing. | 11-18-2010 |
