Abstract

The third harmonic from a Nd:YAG laser is triplet in xenon. The resultant vacuum ultraviolet (VUV) radiation (118 nm) is combined with a visible photon from a dye laser to excite two-photon transitions in Ar and Kr. This method can be used to study many gaseous molecules with transition energies between 11.9 and 16.4 eV. Using this technique, the two-photon rate constants have been measured in Ar and Kr. An expression has been derived for the amount of photoionization by this method and it agrees well with the experiment. The process of VUV generation has also been examined for focused and parallel beams. Data are presented for various factors that affect VUV generation, such as phase-matching by various gases and ionization in the generation cell.
