An in depth characterization of the spectroscopic properties and laser action of 10 at% Yb doped Y3ScxAl5-xO12 (x = 0.25, 0.5, 1.0, 1.5) transparent ceramics

High‐entropy transparent ceramics: Review of potential candidates and recently studied cases

“…% Yb‐doped Y 3 Sc x Al 5‐x O 12 ceramics were studied in detail by changing the Sc content range from x = 0.25 to 1.5. Fabricated ceramic lasers with x = 1.5 were found to exhibit a maximum slope efficiency of 76.6% and the largest tuning range (81 nm) 135 . Solid solution transparent 5 at.…”

“…Solid solution ceramics with disordered structures exhibited broadened absorption and emission spectra 135 . Thus, solid solution transparent garnet ceramics have a special position in the field of lasers.…”

“…Solid solution ceramics with disordered structures exhibited broadened absorption and emission spectra. 135 Thus, solid solution transparent garnet ceramics have a special position in the field of lasers. This discovery resulted from the successful fabrication of transparent Y 3 Sc x Al 5-x O 12 ceramics by Sato et al in 2003.…”

Fabrication and optical properties of garnet ceramics based on Y3−xScxAl5O12 doped with ytterbium and erbium

“…Oxides are one of the most suitable media for doping with erbium and ytterbium as they have high melting points and mechanical characteristics, are stable in a wide temperature range, and have the possibility of doping in a wide concentration range. Recently, studies of oxide compositions based on Y 3 Al 5 O 12 , 3,6,8 Yb 3 Al 5 O 12 , 14,15 Lu 3 Al 5 O 12 , 7,16 Gd 3 Ga 5 O 12 , 17 (Sc x Y 1−x ) 2 O 3 , 18 Gd 3 Sc 2 Ga 3 O 12 , 19 Gd 3 Sc 2 Al 3 O 12 , 20 Y 3 Sc x Al 5−x O 12 (x = 0.25, 0.5, 1.0, 1.5) 21,22 and Lu x Y 3−x Sc 2 Ga 3 O 12 23 have been actively carried out.…”
