Paper Abstract

The peculiarities of energy levels structure of laser-active F3+ color centers in LiF crystals were studied. The dependencies of polarization and fluorescence intensity of LiF crystals with F3+ centers against polarization of powerful laser irradiation which originates two-photon excitation of F3+ centers, were measured and calculated. It was shown that the two-photon transition leads to the excitation of unknown previously spin-singlet electronic state, possessing 1A1 wavefunction symmetry.
