Abstract
Pulsed light is irradiated to an amorphous base material, to produce therein one or more single crystals or polycrystals having nonlinear characteristic advantageous for light communication and laser technique. An external field such as electric field or magnetic field may be applied to the amorphous material, or a seed crystal or crystalline substrate may be used to promote crystallization from a contact interface between the amorphous material and the seed crystal or crystalline substrate.
Claims18
A process for producing an amorphous material containing a crystalline region, comprising the steps of:
- preparing an amorphous base material;
- and
- irradiating pulsed light to the amorphous base material and thereby forming the crystalline region having a nonlinear characteristic in an irradiated portion of the amorphous material.
A selectively crystallized amorphous material comprising:
- an amorphous background region;
- and
- a crystalline region formed in the amorphous background region by irradiation of pulsed light to the amorphous region.
