"My GPS navigator is my favorite electronic toy," the Nobel laureate told his audience. "In my rather large collection," he added with a twinkle. Theodor Haensch, director of the Max Planck Institute of Quantum Optics and sharer of the 2005 Nobel Prize for physics, then summarized for attendees of the Munich Satellite Navigation Summit his work with femtosecond laser frequency combs. This research has the potential to create ultra-precise clocks surpassing, by orders of magnitude, the performance of atomic and hydrogen-maser clocks currently used in navigation satellites, thus further increasing position accuracy.
