ROCKY MOUNTAIN SECTION OPTICAL SOCIETY OF AMERICA & IEEE LASERS AND ELECTROOPTICS SOCIETY March Meeting Date: Thursday, 21 Mar. 2002 Time: 7:00 PM refreshments, 7:30 PM talk Place: National Center for Atmospheric Research Mesa Lab 1850 Table Mesa Drive, Boulder, CO Damon Room Title: Optical Clocks: Timekeeping for the Future Dr. Chris Oates NIST Time and Frequency Division Boulder CO Abstract: As a result of advances in laser cooling, laser stabilization, and frequency metrology, we are now entering a new era of atomic clocks. These clocks, which use optical transitions in atoms, have the potential for orders-of- magnitude improvement over current microwave time standards. In this talk I will first describe the exciting innovations that have made these new clocks viable. Then I will focus on our work with an optical clock that is based on laser-cooled neutral Ca atoms. Biography: Dr. Oates received a B. S. in Physics from Stanford in 1984 and then spent two years in the Caribbean with Peace Corps as a high school science teacher. He completed his doctoral studies at CU in the laboratory of Jan Hall, where he worked on laser trapping and cooling. Since 1995 he has worked in the Time and Frequency Division at NIST, developing optical clocks based on laser-cooled neutral atoms.
