METHOD OF RECORDING OPTICAL INFORMATION IN GLASS Russian patent published in 2015 - IPC G11B7/04

Abstract RU 2543670 C1

FIELD: physics.

SUBSTANCE: silicate glass containing ions and molecular ions of silver, is locally irradiated with femtosecond infrared laser pulses with wavelength of 0.8-1.1 mcm. The irradiated area of the glass then acquires luminescent properties when luminescence is excited by radiation with wavelength of 350-410 nm.

EFFECT: high rate of recording optical information in glass and simple composition of the glass.
