Because of the particular energy-dependence of the scattering, when tossed with the right time delay between tosses, the atoms pass right through one another. The essential achievements are: laser cooling and trapping of atoms (first proposed by Wineland and Dehmelt, and Hänsch and Schawlow), highly stabilized narrow-linewidth cw lasers, and femtosecond optical frequency combs. Combining these key ingredients, we can construct an optical atomic clock as shown schematically in Figure 9. In this research project, we are focusing on drastically simplifying the Yb optical atomic clock.

Operating such clocks requires several laser beams with wavelengths lying within the 670-700 nm spectral range, Using NMR to make a clock The first atomic clock was established at the National Physical Laboratory in 1955 by Louis Essen and John V.L. Parry, but this clock required a roomful of equipment The electronics in 1955 that was required to extract the timing signals from the radio National Institute of Lasers & Optronics · Laser Spectroscopy, Laser Cooling, atomic Clock, Biophotonics, THz Spectroscopy, Semiconductor 2017-10-31 1994-05-01 2020-08-31 The first-stage cooling is 399 nm, second-stage cooling 556 nm, and clock transition 578 nm, and lattice is at 759 nm. The dashed black lines indicate spontaneous decay via other levels. The single-laser simplified version of the Yb optical clock would use only the 556 nm laser for all functions: stimulated slowing of the Yb beam, cooling and trapping in the MOT and also for the “clock 2013-05-04 Simply sticking the atoms into a super-powerful refrigerator won't work, however. The gas containing the atoms would condense on the walls of the refrigerating container, and for atomic clocks, that's no good.

Cooling of atom clouds and single ions by laser irradiation to temperatures close to zero kelvin has considerably advanced the development of atomic clocks and frequency standards. This chapter briefly summarizes first the method to characterize the quality of frequency standards by the Allan standard deviation. The Laser Cooling That Makes Atomic Clocks So Accurate 21 June, 2010 Nobel-Prize winning physicist William Phillips admits that "laser cooling" is a somewhat confusing concept.
