The laser prototype examines the dynamics of cold atoms, By tracking the movements of cold atomic clouds, astronomers can learn a lot about physical processes in the depths of space. To make these measurements, researchers are currently using a device called a “cold-atom inertial sensor” and so far it has controlled in the laboratory.

The insights collected by the team can offer a significant increase in the accuracy of basic physical tests and estimates of the earth’s gravitational field, the dynamics of cold atoms.

Previous studies have made significant progress in the movement of inertia cold motion laser systems that are more concise but have not proven to be suitable for space measurements.

In their study, the researchers’ latest laser system implemented on a ground-based atomic sensor at LNE-SYRTE. This allows them to show that their prototype is ready to conduct real experiments by measuring subtle changes in the Earth’s gravitational field using the interferometry technique of wave material.

His work carried out in collaboration with Sodern in a more general study, conducted by the European Space Agency (ESA), which aims to assess and enhance the maturity of cold atom technology.

The design includes industrial lasers used for telecommunications. with a frequency-doubled. This structure takes advantage of the availability of extensive components and extensive prior studies of the properties of lasers.

Through further testing in the space environment, the team hopes that the system will soon enable researchers to explore various aspects of the physical space environment with an unprecedented level of detail.
