Abstract
The present disclosure provides a system and method for measuring resonance frequencies of a quantum sensor based on multi-photon excitation. The system includes a probe laser module, a coupling laser module, a quantum sensor, a fast measurement module, an experimental signal source, and a measurement and calculation module. The experimental signal source directly faces the quantum sensor, and is configured to transmit a RF electromagnetic signal to the quantum sensor. The quantum sensor includes a closed glass cavity. An alkali metal atomic vapor is enclosed in the glass cavity. The probe laser module is connected to one side of the quantum sensor, and the coupling laser module is connected to the other side of the quantum sensor through the fast measurement module.
