摘要: We investigate the optical detection of single atoms held in a microscopic atom trap close to a surface. Laser light is guided by optical fibers or optical microstructures via the atom to a photodetector. Our results suggest that with present-day technology microcavities can be built around the atom with sufficiently high finesse to permit unambiguous detection of a single atom in the trap with 10 μ s of integration. We compare resonant and nonresonant detection schemes and discuss the requirements for detecting an atom without causing it to …
