Nanofabrication by magnetic focusing of supersonic beams

We present a new method for nanoscale atom lithography. We propose the use of a supersonic atomic beam, which provides an extremely high-brightness and cold source of fast atoms. The atoms are to be focused onto a substrate using a thin magnetic film, into which apertures with widths on the order of 100 nm have been etched. Focused spot sizes near or below 10 nm, with focal lengths on the order of 10 microns, are predicted. This scheme is applicable both to precision patterning of surfaces with metastable atomic beams and to direct deposition of material.Comment: 4 pages, 3 figure

Frequency stabilization of diode laser on the wavelength of 5P

The method of frequency stabilization of diode laser on the wavelength of 5P3/2→5D5/2 of rubidium (776 nm) has been realized. The two-photon absorption spectroscopy of the rubidium vapors is underlie of the suggested scheme. The basic parameters such as the intensity of laser radiation and concentration of the vapors have been investigated. The frequency stability of radiation was about 1 MH

Nanolocalized UV source of laser radiation

We show the results of optical nonlinear interaction of laser light with plasmonic nanostructures. Creation of a nanolocalized source of UV radiation (λ = 260 nm) of the record high intensity was demonstated. Possibility of use of the source for biomedical applications was shown

Single photon transport by a moving atom through sub-wavelength hole

The results of investigation of photon transport through the subwavelength hole in the opaque screen by using single neutral atom are represented. The basis of the proposed and implemented method is the absorption of a photon by a neutral atom immediately before the subwavelength aperture, traveling of the atoms through the hole and emission of a photon on the other side of the screen. Realized method is the alternative approach to existing for photon transport through a subwavelength aperture: 1) self-sustained transmittance of a photon through the aperture according to the Bethe’s model; 2) extra ordinary transmission because of surface-plasmon excitation
