Fabrication of Nd3+:YAG laser ceramics with various approaches

Ce:YAG ceramics: the influence of the synthesis technology features on the luminescent and the optical properties

“…After that, the ceramics were polished. The methods, in which we received optical ceramics earlier [5] underlie the synthesis of these ceramics.…”

Fabrication, optical properties and laser outputs of Nd:YAG ceramics based on laser ablated and pre-calcined powders

“…Besides the lower fabrication temperature, transparent ceramics provide feasibility for stress-free large-sized samples and composite structures such as end caps, absorber edge claddings or gradient doping profile for better laser performance [2e6]. Currently, several scientific groups fabricate laser quality Nd:YAG ceramic using the nanopowders synthesized by different physical and chemical methods [7e12] including laser ablation [13].…”

“…Our previous work [13] reported the fabrication of laser quality Nd:YAG ceramics by the solid-state reaction method with an additional round of pre-calcining from nanopowders synthesized in-house by laser ablation and without the use of any sintering additives (TEOS and/or MgO) and hot isostatic pressing machine. Since the nanoparticles obtained from the laser ablation procedure are very fine and have high reactivity, the formation of the garnet phase starts long before completing the active shrinkage that causes drastic volume changes into powder compact.…”

“…However, the optical quality of YAG-based ceramics obtained from nanopowders produced by the laser ablation method is better when phase transformation into YAG partially occurs before vacuum sintering [20].…”
