High-Resolution Sub-Doppler Laser Spectroscopy

  • Wolfgang Demtröder
Part of the Springer Series in Chemical Physics book series (CHEMICAL, volume 5)


The spectral resolution of all methods discussed in Chap.8 was in principle limited by the Doppler width of lines in the molecular absorption—or emission—spectra, although the laser linewidth might have been much smaller. In this chapter we present several techniques which overcome this resolution limit and which allow one to resolve the natural linewidth even in the presence of a much larger Doppler width. These techniques, which have been developed recently, have already stimulated experimental and theoretical atomic physics in an outstanding way. These various Doppler-free methods certainly represent an important step towards a more detailed knowledge of molecular structure and of deeper details regarding the interaction of E.M. radiation and matter.
