Abstract
Titanium is added in the form of atoms, a colloid, or ions to a glass to be subjected to laser processing in which the ablation or vaporization caused by the energy of an absorbed laser light is utilized. Since titanium can be incorporated into the glass through melting, the threshold value for processing can be easily regulated by changing the amount titanium to be added and a material having evenness in processability can be obtained.
