The application provides a gravimeter probe, and relates to the field of quantum precision measurement.The gravimeter probe comprises a measurement cavity, a containing space in which a vacuum is formed, the containing space being configured to allow a target atomic group in a first energy level to freely fall along a gravity direction and to occur atomic interference in the process of free falling, atoms in the atomic group after the interference being in a quantum superposition state of the first energy level and a second energy level, the first energy level being lower than the second energy level; a light-transmitting part is formed on the measurement cavity and is in communication with the containing space to allow external measurement light to be incident on the containing space from the light-transmitting part; wherein a light beam of the measurement light is configured to cover a movement track of the atomic group after the interference from a first measurement moment to a second measurement moment, the measurement light irradiating the atomic group after the interference at the first measurement moment and the second measurement moment to obtain a transition probability of the target atomic group in the atomic interference, and the transition probability is used to determine a gravity acceleration at a position where the gravimeter probe is located.

The present application belongs to the field of precision measurement, and particularly discloses a method for measuring the transverse temperature of an atomic group in an atomic interferometer. The present application first controls the size of the atomic group at the moment of acting on the Raman light pulse by adjusting the opening time, and then performs a Rabi oscillation experiment under different atomic group sizes. Then, the experimental data are fitted with a trigonometric function, and the key parameters reflecting the transverse temperature are extracted therefrom. Finally, the transverse temperature of the atomic group is obtained by inversion calculation. The method is based on the Gaussian distribution of the atomic group density and the Raman light intensity in the transverse space, and the coupling result of the two is the non-uniformity of atomic transition in the transverse space, thereby affecting the average transition probability of the whole atomic group, i.e. the linearity of the Rabi oscillation curve. Conversely, the linearity of the Rabi oscillation of the atomic group contains the transverse parameters of the atomic group, and the transverse parameters of the atomic group are extracted from the linearity of the Rabi oscillation. The present application can be completed only by relying on the atomic interferometer itself, and has low requirements for equipment, simple process and easy operation.
