Abstract

A 5 at.% Yb³⁺ doped (La_0.10Y_0.90) ₂O₃ transparent ceramic was fabricated with nano-powders and sintered in H₂ atmosphere. Spectroscopic properties and laser performance of Yb:(La_0.10Y_0.90)₂O₃ ceramic were studied. The ceramic exhibits excellent spectroscopic properties, with broad absorption and emission bands, and its refractive index (n) is close to 2. The gain cross-section (σ_g) was calculated at different population inversion ratio (β) values. In addition, among Yb³⁺ doped YAG crystal, Y₂O₃ and (YLa)₂O₃ ceramic, (YLa)₂O₃ ceramic has the least pump intensity (I_min) of 1.25 KW cm^-2. Furthermore, a diode-pumped C-W ceramic laser output has been demonstrated at 1075 nm with a slope-efficiency of 60.2%.
