Abstract
New spin-triplet electronic states of laser-active F3+ color centers in LiF crystals are discovered. The triplet-triplet absorption spectra from low laying 3E state to the high laying states, triplet-triplet 3T(alpha ) yields 3E fluorescence spectrum and 3E yields 1A1 triplet-singlet phosphorescence spectrum are measured. Temperature dependencies of nonradiative singlet-triplet 1E yields 3E and triplet- singlet 3E yields 1A1 transitions probability are found. The influence of spin-triplet states on the LiF:F3+ color center laser characteristics is discussed. The new way of obtaining of tunable oscillation in wide visible range using triplet-triplet transition is offered.
