High Resolution Laser Spectroscopy of Molecules

  • W. Demtröder
Part of the NATO Advanced Study Institutes Series book series (volume 57)


The application of lasers to molecular spectroscopy has indeed revolutionized this field in many respects. Lasers have set new standards with regard to attainable sensitivity and spectral resolution. New sub-Doppler techniques have been developed which overcome the resolution limit imposed on classical spectroscopy by the Doppler-width of molecular lines. The sensitivity limit has been pushed down to the detection of molecular concentrations below the ppb (parts per billion) level. New insights into the nonlinear interaction of molecules with light can be gained by the application of powerful lasers. Multiphoton-spectroscopy, stimulated Raman-scattering or four-wave mixing techniques are only a few examples where new areas of molecular physics have been opened by laser spectroscopy.
