Preparation and laser performance of Nd-doped yttrium lanthanum oxide transparent ceramic

Highly transparent Yb-doped (LaxY1−x)2O3 ceramics prepared through colloidal methods of nanoparticles compaction

“…All of them are heterovalent and vastly reduce laser efficiency, when the ceramics are to be used as hosts to rare-earth ions. Previous investigations revealed a potential of La 2 O 3 to serve as an isovalent aid to sinter both undoped [13] and doped with ether Nd 3+ [14] or Yb 3+ [15][16][17][18] yttria ceramics.…”

Cracks in transparent La-doped yttria ceramics and the formation mechanism

“…E-mail addresses: xmao@siom.ac.cn (X. Mao), lzhang@siom.ac.cn (L. Zhang). matrix of solid solution of La 2 O 3 /Y 2 O 3 had large absorption cross section and emission cross section than those of Y 2 O 3 because of cubic glass-like structure [14], which were liable to achieve the miniaturized LD pumping apparatus and ultra-short mode-locked pulse laser output, respectively [15].…”

Diode-pumped continuous-wave triwavelength ceramic Nd:Y<inf>1.8</inf>La<inf>0.2</inf>O<inf>3</inf> laser

“…In recent years, the sesquioxides of yttrium ceramics have drawn much attention as potential high average power laser host for its high thermal conductivity (13.6 W/mK) and good mechanical properties [1][2]. With a laser diode (LD) as pump, J. Lu et al obtained 160 mW CW operation in Nd:Y 2 O 3 ceramic at 1074.6 nm and 1078.6 nm [3].…”

“…With a laser diode (LD) as pump, J. Lu et al obtained 160 mW CW operation in Nd:Y 2 O 3 ceramic at 1074.6 nm and 1078.6 nm [3]. Recently, yttrium lanthanum oxide (Y 2−2x La 2x O 3 ) transparent ceramics are found to have broad absorption bandwidth [2,4,5]. Output power of 62mW was obtained at 1079 nm in 1.5 at.% Nd:Y 1.8 La 0.2 O 3 ceramic by Qiuhong Yang et al [2].…”
