Paper Abstract

We report on the growth, spectroscopy, and laser emission of two fluoride materials, LiLuF 4 and KY 3 F 10 , doped with Ho 3+ . In particular, laser emission has been obtained for the first time from a Ho 3+ :KY 3 F 10 crystal, grown with the Czochralski technique. Utilizing the micropulling down (μ-PD) method, we grew a Ho 3+ :LiLuF 4 crystal, which allowed us to obtain an efficient laser emission in the 2-μm spectral region. The KY 3 F 10 has a cubic symmetry and it is particularly suitable for technological applications, while the μ-PD technique is appealing for high-power applications. We present the spectroscopic characterization of the two crystals as a function of temperature in the range 10 to 300 K and few laser results.
