Paper Abstract

By using laser selective excitation and low temperature time-resolved spectroscopy techniques, we have been able to experimentally identified the ion centers of tetragonal, trigonal and cubic symmetries in a low concentrated crystal as 0.03%Yb3+:CaF2. This low temperature study was then completed by an analysis of the room temperature spectroscopic properties and of the laser potential of more concentrated Yb3+ doped CaF2 single crystals grown in our laboratory. A laser slope efficiency of 50% with respect to the absorbed 920 nm pump power was obtained, and the laser wavelength could be tuned between 1000 to 1060 nm.
