FLUORESCENCE DYNAMICS IN SOME SOLID-STATE LASER MATERIALS EMITTING IN THE INFRARED REGION : Ho3+DOPED LiYF4SINGLE CRYSTALS AND FLUORIDE GLASSES

Abstract

It is reported on the fluorescence mechanisms of Er3+ and Ho3+ impurity ions in LiYF4 single crystals and in fluoride glasses so‐called BATY and BIZYT with the following compositions: BATY : 20 BaF2–28.75 AlF3–22.5 ThF4– (28.75−x−y) YF3–xHoF3–yErF3. BIZYT : 30 BaF2–30 InF3–20 ZnF2–10 ThF4–(10−x−y) YF3–xHoF3–yErF3.
