Mechanism of degradation of the electronic excitation energy of dye laser molecules
Yu. Kaulakis Vilnius Technical University, Lithuania
Abstract:
An increase in the role of nonradiative electron transitions from an excited state of a dye molecule under the action of a resonant electromagnetic field, together with concentration quenching and luminescence depolarisation, indicate the occurrence of a process which can be called induced degradation of an excited state. A model of interacting oscillators, which emit radiation and convert the electronic excitation energy to heat, makes it possible to account for the main relationships governing the experimentally observed additional quenching. In the first approximation, the general relationships governing the absorption and the concentration effects can be represented in a unified manner and they describe the experimental results with the minimum number of necessary parameters.
