| Outline of Final Research Achievements |
In this research project, we aimed to realize a mixture of an optically trapped nanoparticle and a laser-cooled atomic gas. We built an experimental appratus for trapping a nano-particle in high vacuum. We demonstrated optical trapping of nanoparticles with a single aspherical lens instead of an objective lens, which promises better vacuum condition. We successfully observed the motion of the particle in the optical trap and cooled the temperature down to 1K at the pressure of 10^-3Pa. We analyzed the scattering cross section of a nanoparticle and ultra-cold atoms.
