LASER MATERIAL Russian patent published in 2009 - IPC C30B29/12 C30B11/02 H01S3/16

Abstract RU 2369670 C1

FIELD: physics.

SUBSTANCE: invention relates to electronic engineering material and can be used in making new devices in photonics, quantum electronics and ultraviolet optics. The laser material, based on barium and yttrium fluoride crystal, activated by trivalent ions of cerium BaY₂F₈:Ce³⁺, additionally contains ytterbium and lutetium ions in concentration of 0.5-5.0 at % and 1-5 at %, respectively.

EFFECT: invention allows to reduce coefficient of loss (coefficient of absorption of colour centres) in the wavelength region 300-400 nm, induced by pumping radiation, by 1,5-2,7 times, as well as realising the effect of laser generation on interconfigurational 5d-4f transitions of Ce³⁺ ions in BaY₂F₈ crystals.
