単一周波数795nmCWレーザ光照射による超偏極Xeガス作成の時間変化

抄録

In this study, we attempted to hyperpolarize Xe gas by spin-exchange optical pumping using a CW titanium sapphire laser of 1 W or less. We have found that the progress of hyperpolarization can be investigated by examining the nuclear magnetic resonance signal spectrum for each laser irradiation time.

As a result, under the laser conditions used this time, S/N was remarkably improved when the laser irradiation time was 30 minutes or more, and the nuclear magnetic resonance signal toword hyperpolarized Xe was obtained.
