New Developments in Laser Spectroscopy

Abstract

During the last few years several new ideas have been born and new spectroscopic techniques have been developed that not only improve the spectral resolution and increase the sensitivity for investigating single atoms but that also allow several interesting experiments for testing fundamental concepts of physics. In the historical development of science, experimental progress in the accuracy of measurements has often brought about a refinement of theoretical models or even the introduction of new concepts (Hall in Quantum optics, experimental gravity and measurement theory, Plenum, New York, 1983). Examples include A. Einstein’s theory of special relativity based on the interferometric experiments of Michelson and Morley (Miller in Albert Einstein’s special theory of relativity, Addison-Wesley, Reading, 1981; Heilbron in Max Planck, Hirzel, Stuttgart, 1988), M. Planck’s introduction of quantum physics for the correct explanation of the measured spectral distribution of blackbody radiation, the introduction of the concept of electron spin after the spectroscopic discovery of the fine structure in atomic spectra (Kuhn in Atomic spectra, 2nd edn., Longman, London, 1971; Sobelman in Atomic spectra and radiative transitions, 2nd edn., Springer ser. atoms plasmas, vol. 12, Springer, Berlin, 1992), the test of quantum electrodynamics by precision measurements of the Lamb shift (Lamb and Retherford in Phys. Rev. 72:241, 1947; Phys. Rev. 79:549, 1959) or the still unresolved problem of a possible time dependence of physical fundamental constants, which might be solved by performing extremely accurate optical frequency measurements. In this chapter some of these new and exciting developments are presented.
