Lasers and Atoms for Time and Position


Leo Hollberg, Professor, Physics, Stanford

Seminar Abstract

With precision laser spectroscopy, laser-cooling and trapping of atoms, and femtosecond optical frequency combs, we now have the science and technology to measure Time and space with unprecedented precision. To date, and because of various constraints and bottlenecks, the capabilities of the high performance optical-atomic systems have not yet found their way into real-world applications. Questions arise as to how to optimally leverage quantum systems for fundamental science and applications. One limitation of the highest performance atomic clocks is in transferring Timefrom one location to another. We are exploring the prospects for doing time and frequency transfer, and precise ranging using free-space laser links, with the goal of operating two-way laser links between ground and space. These capabilities would support and enable future scientific missions such as cold atom clocks in space, tests of General Relativity, high accuracy comparison of ground clocks around the world, and perhaps searches for physics beyond the Standard Model. These capabilities could also serve the important function of enhancing the performance of existing GNSS navigation systems as well as precision measurements in earth sciences such as geodesy, sea level determinations and environmental monitoring.
