Abstract
In this communication, we present a spectroscopic study of Dy3+ -doped and Tm3+ -Dy3+ codoped CaF2 as promising candidates to develop solid-state laser sources around 3 μm. In view of the preliminary experimental results, we first demonstrate the advantage of Tm3+ ions as sensitizers to improve the excitation of Dy3+ ions in CaF2 and then is highlighted a singular behavior of Dy3+ doped CaF2 crystals that present a multisite character due to clustering of rare earth ions. The spectroscopic characteristics of each site is studied and discussed, as well as the potential of Tm3+ codoping for laser applications around 3μm.
