Yb<sup>3+</sup>–Er<sup>3+</sup>–codoped phosphate glasses have been studied in the context of research for eye-safe laser source near 1540 nm, wavelength corresponding to the <sup>4</sup>I<sub>13/2</sub>→<sup>4</sup>I<sub>15/2</sub> Er<sup>3+</sup>– transition. Undoped and doped glasses of the composition La<sub>2</sub>O<sub>3</sub>–Li<sub>2</sub>O–P<sub>2</sub>O<sub>5</sub> have been synthesised. Absorption from both the <sup>2</sup>F<sub>7/2</sub> Yb<sup>3+</sup>–ground state and the <sup>4</sup>I<sub>15/2</sub> Er<sup>3+</sup>–ground state, excited state absorption <sup>4</sup>I<sub>13/2</sub>→<sup>4</sup>I<sub>9/2</sub> Er<sup>3+</sup>–transition, emission spectra, decay time measurements and Raman scattering have been investigated by using laser spectroscopic techniques. The Judd-Ofelt intensity parameters Ω<sub>t</sub> (t = 2, 4, 6) for Er<sup>3+</sup> have been calculated in order to determine the radiative lifetimes, the branching ratios of the transitions and the line strength of the excited state absorption <sup>4</sup>I<sub>13/2</sub>→<sup>4</sup>I<sub>9/2</sub>. A thermal conductivity measurement has also been realised. In this paper, the Mayn spectroscopic properties of Yb<sup>3+</sup>–Er<sup>3+</sup>–codoped LaLiP<sub>4</sub>O<sub>12</sub> will be discussed and compared with other Yb<sup>3+</sup>–Er<sup>3+</sup>–codoped phosphate glasses. |
