| Zusammenfassung | With laser spectroscopic techniques used so far, measurements of atomic number densities in flames and other combustion processes at atmospheric pressure yield no satisfying results because high quenching rates remarkably reduce the signal size and the results suffer from large uncertainties. Two-photon polarization spectroscopy is not limited by quenching and has been used for the determination of the number density and the kinetic temperature of atomic hydrogen in flames for the first time. The great potential of this method comes into its own only in conjunction with laser radiation of highest possible quality in the UV, i.e. 2.5 ns laser pulses with energies of up to 10mJ wihin a bandwidth of 300 MHz, tunable around 243 nm. |
