Abstract

Laser induced fluorescence of the mercury clusters Hg2 and Hg3 in the spectral range between 300 nm to 510 nm has been obtained from the dissociation of HgBr2 at 7.88 eV (157.5 nm) with an F2 molecular laser, together with fluorescence from mercury atomic transitions from highly excited states. The excitation process involves two photon absorption which dissociates the molecule at 15.76 eV total photon energy with the subsequent formation of the metallic clusters.

    The term superfluorescence is used to decribe strong directional emission and could refer as amplified spontaneous emission, stimulated emission or laser emission. A discrimination between these terms is rather difficult [23]Google Scholar
