Other Abstract | The invention discloses a preceding-stage atom pre-cooling system suitable for a cold atom experiment, which is communicated with an experiment cavity and comprises a glass cavity used for receiving atoms to be cooled; the vacuum cavity assembly is used for maintaining the pressure difference between the glass cavity and the experiment cavity and providing a transmission channel for the cooled atomic group; the horizontal cooling device is used for expanding the horizontal cooling laser beam into an elliptical light spot and emitting the elliptical light spot to cool the atomic group in the horizontal direction; the vertical direction cooling device is used for expanding the vertical cooling laser beam into an elliptical light spot and emitting the elliptical light spot to cool the atomic group in the vertical direction; the gradient magnetic field coil assembly is used for providing a gradient magnetic field; and the atomic group pushing assembly is arranged on one side of the glass cavity and is used for emitting a group of pushing laser to push the cooled atomic group from the glass cavity into the experiment cavity. According to the method, the temperature of an atomic group can be lower, the optical thickness is higher, and the atomic flux is larger. |
