Paper Abstract

A relatively new method of atomic DeBroglie wave transmission in a hollow single mode optical fiber is presented. A slightly blue-detuned, from the atomic resonance, optical evanescent wave in the ring core of the capillary optical fiber creates a potential barrier for co-propagating or counter-propagating DeBroglie wave. The applied optical wavelength, associated with the used atomic transitions, was in the range 1100-400nm. Excited, metastable atoms of chromium, rubidium, cesium, helium, alkalis, etc., were transmitted in the capillary optical fiber. Initially the transmission was multimode and then single mode, with increasing efficiency. There are considered initial application perspectives of this transmission technology of DeBroglie wave for building of coherent cold sources of atoms, atom interferometers, and devices of the inverse lithography, which may possibly compete with the short-wave photo-lithography. The paper is a tutorial and has a teaching and technology review character.
