Fabrication and characteristics of neodymium-activated yttrium oxide optical ceramics

Interaction of the radiation of the high-power ytterbium-fiber laser with inhomogeneous dielectric targets

“…In a series of the test calculations, we employ the data on the radiation absorption for the Nd:Y 2 O 3 ceramic samples with different transparencies that are obtained by A.N. Orlov using the method from [12,13]. The results of these calculations are compared with the experimental results.…”

“…We employ α 0 = 10 cm -1 for the transparent melt based on (1) and (3) calculated curves of the evaporated mass and (2) and (4) the results for the ceramic samples with similar mor phology [13]. Figure 8 shows the dynamics of the temperature field in the two layer target for radiation powers of 700 and 500 W (panels (a) and (b), respectively).…”

Fabrication and optical properties of Y2O3-based ceramics with broad emission bandwidth

“…10 The transformation of monoclinic phase in a main cubic is accompanied by substantial growth of elementary cell volume. Therefore in order to avoid destruction of ceramic sample during sintering the phase transformation was performed in advance by annealing of all pellets at 800-1100 • C for 3 h in air.…”

Sintering Conditions for Al2(WO4)3High-Dense Ceramic

“…The technology of optical ceramics includes three main stages: (1) fabrication of nanopowders (2) preparing of * corresponding author; e-mail: a.yordanova@svr.igic.bas.bg highly dense compacts, and (3) sintering of the compact to the non-porous ceramics [6]. In this article we present the next step of the investigation sintering of high dense compact Al 2 (WO 4 ) 3 ceramics as a main member of these tungstates by cold pressing and additional sintering as well as by hot pressure sintering.…”
