The work presented here was concerned with the development and characterization of an optical frequency standard based on laser-cooled "4"0Ca atoms. For the realization of such a standard the frequency of a laser is stabilized to the narrow line of the clock transition of calcium at 657 nm. A frequency standard with cold Ca atoms at a temperature o...

In der vorgelegten Studie wurde geprueft, ob die gepulste elektromagnetische Hochfrequenz-Strahlung eines Mobilfunktelefons im D-Netz-Betrieb die Funktion der Sinneszellen des menschlichen Hoerorgans beeinflusst. Die Funktion der Hoersinneszellen wurde mit Hilfe der otoakustischen Emissionen erfasst. Otoakustische Emissionen sind Schallaussendungen...
The study of hydrogen and hydrogenic (one-electron) ions is an area of rapid progress and one of great potential for future frequency standards. In 1997, the two-photon 1S-2S transition in the hydrogen atom was included in the list of approved radiations for the practical realisation of the metre, and since then revolutions in optical frequency met...
