Rydberg atomic electric field sensing device and system

The invention discloses a Rydberg atomic electric field sensing device and system which are applied to the field of quantum sensing, the device comprises an atomic gas chamber, a first distributed feedback laser and a second distributed feedback laser, the first distributed feedback laser and the second distributed feedback laser each comprise a laser source resonant cavity formed inside, the first distributed feedback laser and the second distributed feedback laser take laser generated by light feedback and light amplification based on respective internal laser source resonant cavities as probe light and pump light respectively and enter from one side of the atomic gas chamber, so that atoms in the atomic gas chamber reach an excited state and a Rydberg state in sequence. The distributed feedback laser is used as pump light and probe light for exciting Rydberg atoms, a miniaturized light source is provided for the Rydberg atom electric field sensing device, the integration level of the device is improved, th
