“…In addition, the mixed solvent is expected to weaken the absorption of hydroxyl on the particle surfaces and the steric effect of ethanol may also hinder particles from moving closer to each other, which is in favor of better dispersity. The nano-powder exhibits a specific surface area (S BET ) of 6.626 m 2 /g with an average particle size (D BET ) of 96 nm which is calculated according to the formula [37]:…”

The Yb:Lu2O3 precursor made up of spherical particles was synthesized through the co-precipitation method in the water/ethanol solvent. The 5 at% Yb:Lu2O3 powder is in the cubic phase after calcination at 1100 °C for 4 h. The powder also consists of spherical nanoparticles with the average particle and grain sizes of 96 and 49 nm, respectively. The average grain size of the pre-sintered ceramic sample is 526 nm and that of the sample by hot isostatic pressing grows to 612 nm. The 1.0 mm-thick sample has an in-line transmittance of 81.6% (theoretical value of 82.2%) at 1100 nm. The largest absorption cross-section at 976 nm is 0.96×10−20 cm2 with the emission cross-section at 1033 nm of 0.92×10−20 cm2 and the gain cross sections are calculated with the smallest population inversion parameter β of 0.059. The highest slope efficiency of 68.7% with the optical efficiency of 65.1% is obtained at 1033.3 nm in quasi-continuous wave (QCW) pumping. In the case of continuous wave (CW) pumping, the highest slope efficiency is 61.0% with the optical efficiency of 54.1%. The obtained laser performance indicates that Yb:Lu2O3 ceramics have excellent resistance to thermal load stresses, which shows great potential in high-power solid-state laser applications.

“…Lanthana (La 2 O 3 ) is another efficient sintering additive [15]. The 10 mol% La:Y 2 O 3 solid solution is consolidated into laser-quality ceramics only by free vacuum sintering (without subsequent HIPing), as demonstrated previously for (Yb x La 0.10 Y 0.9-x ) 2 O 3 ceramics [16][17][18].…”

A transparent sesquioxide ceramic (Er0.07La0.10Y0.83)2O3 was fabricated by vacuum sintering at 1780 °C for 3 h with lanthana acting as a sintering additive. It was of single-phase nature (sp. gr. Ia 3 ˉ ) with a close-packed microstructure (average grain size: 17 μm, pore content: 5 ppmv) and high transparency of 80% at 1.1 μm. The La3+ ions induced additional inhomogeneous broadening in the absorption and emission spectra of Er3+ ions. For the 4I11/2→4I13/2 transition, the stimulated-emission cross-section σ SE was 1.06 × 10−20 cm2 at 2719 nm and the luminescence lifetimes of the 4I11/2/4I13/2 states amounted to 2.73/5.91 ms, respectively. A (Er0.07La0.10Y0.83)2O3 ceramic laser generated 300 mW at 2840 nm with a slope efficiency of 27.7% and a laser threshold of only 17 mW.

“…Another efficient sintering aid is La2O3. The introduction of about 10 mol% La2O3 notably promotes the diffusion of ions [9,10] leading to the fabrication of Yb:Y2O3 laser ceramics [11]. As compared to ceramics with heterovalent sintering aids, such materials do not exhibit degradation of their laser properties with time.…”
