technique of precise atom control using near-field light. In the demonstration
experiments, cold Rb atoms deflected by repulsive near-field light induced in a
200 nm-wide slit are detected by means of two-step photoionization. Then, we
consider a near-field-light lens of atomic de Broglie waves by developing the
atom deflector. The feasibility of nanofocusing is shown by numerical analyses
with Fourier atom optics. Finally, we describe atom funnels with evanescent
light to generate a cold atomic beam required for atom manipulation using
nanometric near-field light. The flux intensity of cold Rb atoms outputted from a
240 µm outlet is estimated
to be 7.5 × 107 atom cm−2 s−1 at a blue
detuning of 1.2 GHz. In order to increase the flux intensity to
1012 atom cm−2 s−1, we develop a Si-made funnel with a micron-sized outlet.},
