Abstract
The present application discloses a control method for fast trapping and high-frequency mutual ejection of cold atom groups. The control method includes: arranging three groups of optical stops on three groups of light sources (splitters) in three-dimensional magneto-optical traps, to form a shaded regions; ejecting a cold atom group from the first three-dimensional magneto-optical trap along a movement trajectory to the second three-dimensional magneto-optical trap, where the movement trajectory passes through the shaded regions of the two three-dimensional magneto-optical traps; and, when it is determined that the cold atom group enters the shaded region of the first three-dimensional magneto-optical trap, trapping a next cold atom group by turning on three-dimensional cooling light and three-dimensional repumping light in the first three-dimensional magneto-optical trap.
