Abstract
A method of manufacturing a crystal device includes applying substantially simultaneously a first light that is absorbed by a crystal plate and excites an energy level of a substance constituting the crystal plate from a ground state to a first excited state, and a second light that excites the energy level of the substance constituting the crystal plate from the first excited state to a second excited state to generate an ablation, thereby forming one or more grooves in a predetermined pattern on the crystal plate.
