磁光阱是一种囚禁中性原子的有效手段．它由三对两两相互垂直、具有特定们振组态并且负失谐的对射激光束形成的三维空间驻波场和反向亥姆雷兹线圈产生的梯度磁场构成，磁场的零点与光场的中心重合，负失谐的激光对原子产生阻尼力，梯度磁场与激光的偏振相结合产生了对原子的回?
Magneto-optical trap is an effective means of trapping neutral atoms. It consists of three pairs of two perpendicular to each other, with specific vibration configuration and negative detuning of the laser beam formed by the three-dimensional space standing wave field and the reverse gradient Helmutz magnetic field coil composition, the magnetic field zero and light The center of the field is coincident, the negative detuning laser produces a damping force on the atom, and the combination of the gradient magnetic field and the polarization of the laser produces a return to the atom.
