Useful model relates to computer engineering and can be used at creation of memory devices and devices data processing base on photon echo. Photon echo-processor with laser cooling contains a source of excitation photon echo impulses and radiation source of pumping the anti-Stokes cooling, optically connected with the solid-state information carrier, which is optically coupled with device of recording signals photon echo. Solid-state data carrier is made from material, containing 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 ions of another rare-earth element, for example trivalent ytterbium, which are evenly distributed in the material of the solid-state data carrier. Solid-state data carrier can be made in the form of active light guide, 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 uniformity of distribution of centers of anti-Stokes cooling is equalized cooling temperature centers of the excitation photon echo along the whole volume of the solid-state data carrier, that provides error information processing in echo processor.
