PHOTON ECHO-PROCESSOR WITH LASER COOLING Russian patent published in 2009 - IPC G11C13/04 

FIELD: physics, computer engineering.

SUBSTANCE: present invention relates to computer engineering and can be used during the creation of data storage medium and information-processing device based on a photon echo. The photon echo-processor with laser cooling contains a pumping source of the photon echo impulses and radiation source of pumping the anti-Stokes cooling, optically connected with the solid-state data carrier. The solid-state data carrier is made from material, which contains the excitation centres of the photon echo on ions of one of the rare-earth elements, for example trivalent thulium, and centres of anti-Stokes cooling on the ions of another rare-earth element, which are evenly distributed in the material of the solid-state data carrier. The solid-state data carrier can be made in the form of a light-guide fiber, whose core is made from material, containing excitation centres of the photon echo, and the cladding is made from material, containing centers of anti-Stokes cooling. Due to the uniformity of distribution of the centres of anti-Stoke cooling there is evenness of the cooling temperature of excitation centers of the photon echo on the whole of the solid-state data carrier, which provides for the elimination of errors during information processing in the echo-processor.

EFFECT: elimination of errors during information processing in the echo-processor.
