Outline of Final Research Achievements	The principal investigator was transferred from Titech to Shizuoka Univ. at the start of this research. So it was a purpose of this research to reappear the previous research and to develop that. In the previous research, our main object was rubidium atoms. In this research we would attend to develop a laser cooling system of cesium atoms. We produced laser systems for manipulation of cesium atoms, and recognized that the laser systems work as expected by spectroscopy with a cesium glass cell. Then, we performed several experiments and recognized features of the cesium atoms with that laser system. On the other hand, we recognized that we realized laser cooling of rubidium atoms in this research, which was performed in the previous research.
