| dc.description.abstract | Er3þ and Yb3þ doped cubic elpasolite Cs2NaYF6 crystals including stoichiometric compositions Cs2NaErF6 and Cs2NaYbF6 have been synthesized under hydrothermal conditions. Absorption, stimulated-emission and gain cross-sections spectra have been determined for the 2F5/2-2F7/2 (Yb3þ) and 4I13/2-4I15/2 (Er3þ) transitions at room-temperature. The maximum σSE values are 1.8 10 21 cm2 at 993 nm (Yb3þ) and 3.8 10 21 cm2 at 1535 nm (Er3þ). Elpasolite crystals provide exceptionally long radiative lifetimes of the excited-states for both ions, namely τ(2F5/2)¼6.3 ms and τ(4I13/2) 32 ms for 10 at% Yb3þ:Cs2NaYF6 and 10 at% Er3þ:Cs2NaYF6 which can be used in high pulse energy Q-switched lasers. Up-conversion luminescence has been studied for Er3þ doped and Er3þ, Yb3þ codoped Cs2NaYF6 crystals. | en |
