Glass suitable for optical functional elements and process for producing same

A glass suitable for optical functional elements, said glass comprising:

• a matrix comprising a compound of at least one nonmetallic element;
• and
• a particle selectively formed in said matrix, said particle being made of said at least one nonmetallic element dissociated from said compound by condensing a pulsed laser beam in said matrix,
• wherein said compound is an organic compound such that said particle is made of carbon.

A glass suitable for optical functional elements, said glass comprising:

• a matrix comprising a compound of at least one nonmetallic element;
• and
• a particle selectively formed in said matrix, said particle being made of said at least one nonmetallic element dissociated from said compound by condensing a pulsed laser beam in said matrix,
• wherein a cation of said matrix of said glass is less reducible than an ion of said at least one nonmetallic element.

A process for producing a glass suitable for optical functional elements, said process comprising:

• (a) providing a blank glass that is a raw material of said glass, said blank glass comprising a compound of at least one nonmetallic element;
• (b) condensing a pulsed laser beam to a focal point in said blank glass such that a particle is selectively formed in said blank glass at a position corresponding to said focal point, said particle being made of said at least one nonmetallic element dissociated from said compound;
• and
• (c) moving said focal point in said blank glass to produce a pattern of said particle.
