Optical properties of Dy:YCa4O(BO3)3 crystal grown by the Czochralski technique
Dy ^3+ -doped YCa _4 O(BO _3 ) _3 (Dy:YCOB) crystal was successfully grown by the Czochralski technique. The absorption cross section at 453 nm was 0.28 × 10 ^–21 cm ^2 , that is related to the ^6 H _15/2 → ^4 I _15/2 transition. The Judd-Ofelt parameters Ω _t (t = 2, 4, 6) were 1.62 × 10 ^–20 , 0...

| Summary: | Dy ^3+ -doped YCa _4 O(BO _3 ) _3 (Dy:YCOB) crystal was successfully grown by the Czochralski technique. The absorption cross section at 453 nm was 0.28 × 10 ^–21 cm ^2 , that is related to the ^6 H _15/2 → ^4 I _15/2 transition. The Judd-Ofelt parameters Ω _t (t = 2, 4, 6) were 1.62 × 10 ^–20 , 0.10 × 10 ^–20 , 0.41 × 10 ^–20 cm ^2 , respectively. The emission cross section assigned to the transition ^4 F _9/2 → ^6 H _13/2 was 1.02 × 10 ^–21 cm ^2 . The ^4 F _9/2 energy level’s fluorescence lifetime was 900 μ s. |
