We propose and demonstrate a scheme for Doppler compensated optical cavity enhancement of atom interferometers at significantly increased mode diameters. This overcomes the primary limitations in cavity enhancement for atom interferometry, circumventing the cavity linewidth limit and enabling spatial mode filtering, power enhancement, and a large beam diameter simultaneously. This approach combines a magnified linear cavity with an intracavity Pockels cell.

- A new quantum gravity gradient sensor has been developed to improve the precision of gravity measurements in geophysics, particularly for applications in engineering and climate research.
- The sensor significantly reduces vibrational noise and achieves high statistical accuracy, allowing for detailed underground surveys, such as detecting a 2-meter tunnel with a high signal-to-noise ratio.
- Its capabilities can be applied to diverse fields, including aquifer mapping, archaeology, soil property analysis, and assessing construction site conditions, enhancing our understanding of subsurface features.
