Abstract

Several detection techniques of laser spectroscopy are discussed. The techniques are either based on modified absorption spectroscopy with frequency or wavelength modulation, opto-acoustic and opto-thermal spectroscopy, laser induced fluorescence or on resonant two photon ionization. A comparative study of the techniques with their advantages and disadvantages is also presented. Modulated absorption spectroscopy is one laser spectroscopy technique that can be used in cells as well as in molecular beams. Opto-acoustic spectroscopy needs a buffer gas in order to transfer the excitation energy sufficiently fast into translational energy.
