| 20080218735 | Laser Processing Method And Device - A laser processing method which can efficiently perform laser processing while minimizing the deviation of the converging point of a laser beam in end parts of an object to be processed is provided. | 09-11-2008 |
| 20080251506 | Laser Processing Method and Device - A laser processing method which can efficiently perform laser processing while minimizing the deviation of the converging point of a laser beam in end parts of an object to be processed is provided. | 10-16-2008 |
| 20090032509 | Laser Machining Method - A laser processing method which can reduce the chipping generated when a plate-like object to be processed formed with a modified region is turned into small pieces in steps other than its dividing step. | 02-05-2009 |
| 20090039559 | Laser Beam Machining Method - To provide a laser processing method which can highly accurately cut a planar object to be processed having an irregular surface as an entrance surface for processing laser light. | 02-12-2009 |
| 20090166342 | Laser Material Processing System - A laser processing apparatus comprises a converging lens | 07-02-2009 |
| 20100006548 | LASER WORKING METHOD - A converging point of processing laser light is made to accurately follow a laser light irradiation surface of an object to be processed. An object to be processed | 01-14-2010 |
| 20100012633 | LASER PROCESSING METHOD - A modified region is accurately formed at a desirable position with respect to a laser light irradiation surface of an object to be processed. When an average difference γ has a value exceeding a predetermined threshold during trace recording, a particle segment Z including a line segment S where the average difference γ exceeds the predetermined threshold is defined. This determines that a particle exists on a line to cut | 01-21-2010 |
| 20100025386 | LASER PROCESSING DEVICE - The time required for forming a modified region within an object to be processed is shortened. An apparatus | 02-04-2010 |
