Abstract
The paper reports on a measurement and calculation of the dependence of LiF : F-2 luminescence polarization and intensity on the polarization of high- power laser radiation (lambda(ex) = 1064 nm) producing two-photon excitatio n of F-2 centers. It is shown that the two-photon transition results in the excitation of a previously unknown electronic level of F-2 centers of the A(1g) symmetry. (C) 2000 MAIK "Nauka/Interperiodica".
