Recent developments in quantum technology have resulted a new generation of sensors for measuring inertial quantities, such as acceleration and rotation. These can exhibit unprecedented sensitivity accuracy when operated space, where the free-fall interrogation time be extended at will environment noise is minimal. European laboratories played leading role this field by developing concepts tools to operate these relevant environment, parabolic flights, towers, or sounding rockets. With...
Compact vacuum systems are key enabling components for cold atom technologies, facilitating extremely accurate sensing applications. There has been important progress toward a truly portable compact system; however, size, weight, and power consumption can be prohibitively large, optical access may limited, active pumping is often required. Here, we present centiliter-scale ceramic chamber with He-impermeable viewports an integrated diffractive optic, robust laser cooling light from single...
Grating magneto-optical traps are an enabling quantum technology for portable metrological devices with ultracold atoms. However, beam diffraction efficiency and angle affected by wavelength, creating a single-optic design challenge laser cooling in two stages at distinct wavelengths – as commonly used loading, e.g., Sr or Yb atoms into optical lattice tweezer clocks. Here, we optically characterize wide variety of binary gratings different to find simple empirical fit experimental grating...
We demonstrate the integration of micro-electro-mechanical-systems (MEMS) scanning mirrors as active elements for local optical pumping ultra-cold atoms in a magneto-optical trap. A pair MEMS steer focused resonant beam through cloud trapped shelved F = 1 ground-state 87 Rb spatially selective fluorescence atom cloud. Two-dimensional control is demonstrated by forming geometrical patterns along imaging axis cold ensemble. Such atomic ensemble with microfabricated mirror could find...

Here we present a cold atom system, small enough to be handheld, and suitable for use in sensor. This has been achieved by developing compact robust components laser cooling. Notably integrating centilitre scale vacuum system diffractive grating magneto-optical trap optics key step creating this system. The performance of these is discussed, including the validation using atoms measure pressure. Future improvements are outlined.
