Polarization labeling

A typical experimental arrangement used in our lab for studying molecular Rydberg states is exhibited in Fig. 5.38. The pump laser is a single-mode cw dye laser, which is amplified in two pulsed amplifier cells pumped by a nitrogen or excimer laser. The spectral continuum is provided by the broad fluorescence excited in a dye cell by part of the excimer laser beam. Since this spectral continuum is only formed within the small pump region in the dye cell, it can be transformed

A very powerful method for the assignment of complex molecular spectra is the "polarization labelling technique", which is based on a combination of polarization spectroscopy and optical double resonance. This method employs two different lasers (see Fig.10.42). The output beam from the first laser is...
