Optical Atomic Clock: A long look at the captured atoms
In the case of one of the candidates for an optical clock which is developed at Physikalisch-Technische Bundesanstalt, an optical grating clock with strontium atoms, the loading of cold atoms into an optical grating has been optimized to such an extent that approx. 106 strontium atoms are loaded into the grating within 150 milliseconds at a temperature of a few microkelvin. There, the atoms remain stored for over one second and are available for a precision measurement of the optical frequency. (2008-02-05)
