AI Technical Summary

Technical Problem

Traditional Rydberg atomic electric field sensor technology is complex, bulky, and expensive, making it difficult to apply in non-laboratory environments.

Method used

A narrow-linewidth distributed feedback laser is used as both the probe and pump light. Laser amplification and feedback are achieved through the internal laser source resonant cavity of the distributed feedback laser. This is integrated into the Rydberg atomic electric field sensing device. The optical path is optimized using coupling optical fibers and focusing lenses, and the optical path is separated by a beam splitter prism to reduce losses and improve accuracy.

Benefits of technology

This technology enables the miniaturization of the Rydberg atomic electric field sensing device, making it suitable for non-laboratory environments, easy to move and integrate, and improving measurement accuracy and device integration.
