Atom-by-Atom Assembly of Defect-Free One-Dimensional Cold Atom Arrays

November 7, 2016

This image shows the basic setup that enables researchers to use lasers as optical “tweezers” to pick individual atoms out from a cloud and hold them in place. The atoms are imaged onto a camera, and the traps are generated by a laser that is split into many different focused laser beams. This allows a single atom to be trapped at each focus.
