| Outline of Final Research Achievements |
I am trying to make a transparent detector to light which distinguishes whether light is passed or not. For this purpose, I am constructing a system, where an atom is placed between two mirrors (optical resonator) and the spin direction of the atom (angular momentum) is operated by light. Thanks to this KAKENHI support, I created a frequency stabilization system so that the lasers using a titanium sapphire crystal and a semiconductor can emit light at resonant frequencies of atomic transitions. In addition, I developed the spatial distribution measurement of light for the purpose of laser machining of the resonator mirrors.
