MANUFACTURING METHOD OF SMALL-SIZED ATOMIC CELLS WITH VAPOURS OF ATOMS OF ALKALINE METALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC C03B23/20 G04F5/14 

FIELD: metallurgy.

SUBSTANCE: manufacturing method of atomic cells involves heating of an opening and an end face of a cell workpiece, welding of the opening to one of the end faces of the workpiece and their annealing by emission of a CO₂ laser, heat treatment of the workpiece, pumping-out and further filling with vapours of alkaline metal in vacuum. Then, the sputtered metal is evaporated from workpiece walls by means of the CO₂ laser and the cell is sealed by installation of a transparent opening on the second end face of the cell workpiece and its welding to the end face by means of a laser. A device for filling in the cells with alkaline metal includes a vacuum chamber, pumps and a laser system. The vacuum chamber includes a carrousel with seats, a workpiece heater, a cover plate laying mechanism, and an opening transparent for laser emission.

EFFECT: invention allows obtaining miniature atomic cells with improved light transmission and operating properties, and allows saving an isotope of alkaline metal.
