| Outline of Final Research Achievements |
Analytical technique based on fracture mechanics was established to set the optimum scribe processing condition with laser scribing method for laminated chemically tempered glass. Superiority of laser scribing experiment using scribing condition obtained from numerical analysis was confirmed. In addition, as a processing method to generate flaw that is indispensable for a laser scribe processing, laser ablation which is laser processing technique with ultra-short pulsed laser will be applied. About ablation processing, analytical technique to get ablation processing condition was established, and effectiveness by laser ablation experiment using analytical result was confirmed. We elucidated fracture mechanism by interaction of laser beam and glass and contributed to application to laser processing using a fracture phenomenon.
