| description | A transparent 2 at% Nd<sup>3+</sup>-doped Lu<sub>3</sub>Al<sub>5</sub>O<sub>12</sub> (LuAG) ceramic was fabricated by using tape-casting method and solid-state sintering technology. Based on the room temperature absorption spectrum, the three J-O intensity parameters were calculated with Judd-Ofelt analysis, and then, the radiative transition rates and branching ratios of transitions from <sup>4</sup>F<sub>3/2</sub> manifold to the 4I<sub>J'</sub> (J' = 13/2, 11/2, 9/2) lower lying multiple manifolds were determined. The quantum efficiency of 80.4% was evaluated from the measured fluorescence lifetime and the radiative lifetime of the <sup>4</sup>F<sub>3/2</sub> manifold state. Also, the inter-Stark energy levels of the 4I.<sub>J'</sub> manifolds were performed, and the peak emission cross sections of the <sup>4</sup>F<sub>3/2</sub> → 4I<sub>J'</sub> intermanifold transitions were determined. The total emission cross section for <sup>4</sup>F<sub>3/2</sub> → <sup>4</sup>I<sub>9/2</sub>, <sup>4</sup>I<sup>11/2</sup>, and <sup>4</sup>I<sub>13/2</sub> transitions was calculated to be 7.41 × 10<sup>-20</sup> cm<sup>2</sup>, 29.83 × 10<sup>-20</sup> cm<sup>2</sup>, and 10.53 × 10<sup>-20</sup> cm<sup>2</sup>, respectively. Finally, under an 808 nm diode laser pumping, the continuous wave laser performances of the Nd:LuAG transparent ceramic were investigated. |
