Better Lasers and Atomic Traps Yield Better Timekeeping
Investigators from JILA, a research institute jointly administered by the National Institute of Standards and Technology (NIST) and the University of Colorado in Boulder, have developed the basics for the most precise optical atomic clock produced to date. They have devised a way to produce a “tick” 100 times more precise than those generated by current microwave-based standards.
Lead investigator Jun Ye, a JILA and NIST fellow as well as an adjoint professor of physics at the university,...
