Astronomers Can Learn About the Physical Processes by Tracking the Motions of Cold Atom Clouds

By tracking the movements of cold atom clouds, astronomers can study a lot in regard to the bodily processes which play out within the depths of space. To make these measurements, researchers at present use instruments named ‘cold-atom inertial sensors, ‘ which, to this point, have largely been operated contained in the lab. In new work revealed in EPJ D, a group of physicists at Muquans and LNE-SYRTE current an innovative prototype for a new industrial laser system. Their design paves the way in which for the development of cold-atom inertial sensors in space.

The insights gathered by the group may supply important improvements within the accuracy of tests of fundamental physics, in addition to assessments of the Earth’s gravitational subject. Research up to now has made important strides towards mobile laser techniques for cold atom inertial sensing that are extra compact; however, these haven’t but widely proven appropriate for measurements in space. In their research, the researchers’ up to date laser system was applied onto a ground-based atomic sensor at LNE-SYRTE. This enabled them to show that their prototype was prepared to hold out actual experiments measuring the subtle variations within the Earth’s gravitational field utilizing matter-wave interferometry techniques.

The design includes industrial lasers that are sometimes used for telecommunications, with their frequencies doubled. This setup benefited from a large availability of components, in addition to extensive earlier analysis into the properties of the lasers. Through additional testing in space-like environments, the group hopes that their system might soon permit researchers to probe numerous aspects of the physical environment of space in unprecedented levels of detail.
