| Research Abstract |
We have setup the vacuum chamber to polarize nuclear-spin of Yb target, and developed the narrow-band ns laser system to optically monitor the resonantly excited and then photoionized Yb ions. Moreover, we have theoretically considered a new scheme to efficiently polarize nuclear-spin of target atoms using a sequence of short laser pulses. As a specific example we apply the idea to the muonium, a kind of exotic atom, and found that the irradiation of five resonant pulses with a duration of 1 ps and time interval of 5 ns results in 80% polarization.
