Transparent polycrystalline ZnAl 2 O 4 (gahnite) ceramic doped with 0.1 at.% Co 2+ is
synthesized by hot pressing of powders (1600° C, 50 MPa) using the sintering additive, ZnF …

Yttrium aluminum garnet optical ceramics (Y 3− x Ca x Al 4. 95 Cr 0. 05 O 12) doped with 0.1
at.% of chromium ions and 0.5, 0.8 and 1.2 at.% of calcium ions were prepared by reactive …

We describe the development of a reasonable cost Co 2+: MgAl 2 O 4 transparent ceramic
plates fabrication technology that allows the producing of parts functioning as passive laser …

In the present work we provide an analysis of the accuracy of the calculation of Cr 4+
concentration in Cr 4+: YAG using absorption spectroscopy. Avizonis-Grotbeck theory and …

This paper focuses on the kinetics of Cr 4+ formation in Cr, Ca: YAG ceramics prepared by
solid-state reaction sintering. The kinetics of Cr 4+ formation was studied by annealing of Cr …

A new approach to producing of transparent bulk ZnAl 2 O 4 ceramics based on hot pressing
of powders (1600° С, 50 МPа) in presence of sintering additive ZnF 2 is described. Using …

Cobalt-doped magnesium aluminate spinel (Co: MgAl 2 O 4) is one of the most important
saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe …

Single-stage processing of high-quality transparent functional polycrystalline ceramics is
desirable but challenging. In the present work, spark plasma sintering (SPS) was employed …

Co-doped magnesium aluminate (Co: MgAl 2 O 4) transparent ceramics were obtained by
pre-sintering in air and hot isostatic pressing (HIP) with commercial spinel and CoO powders …
