| Outline of Final Research Achievements |
Although the generation of coherent electromagnetic field has already reached the X-ray region, experimental studies on the interaction with single atomic systems remain in the deep ultraviolet region. When spectroscopy for such single atoms in the vacuum ultraviolet region is realized, the path to new applications such as high-precision verification of quantum electromagnetics and optical frequency standard using nuclear transitions could be opened up. We experimentally generated coherent vacuum ultraviolet light with an average power of a few μW (micro watt), and concretely estimated a detection rate of fluorescence from a singly trapped ion excited by the vacuum ultraviolet light, by taking into account the loss of the optical system. In order to realize this configuration, in this research, we developed an optical system that can efficiently focus vacuum ultraviolet light to a single atom and can image fluorescence from excited atoms with high efficiency.
