Scientists Advance the Technology of High-Speed Sintering for Optical Ceramics Written by AZoOpticsFeb 5 2021 Scientists of Far Eastern Federal University (FEFU) have advanced the technology of high-speed sintering for optical ceramics (Nd3+:YAG), i.e. active elements generating laser emission in the near-infrared wavelength range (1.06 μm) for cutting the edge microelectronics and medicine. The researchers have managed to reduce significantly the initial nanopowders consolidation period (10 - 100 times) forming a nanostructure with ensured high optical transparency of the ceramic material. A related article appears in Optical Materials. Diode-pumped microlasers based on Nd3+:YAG nanoceramics, due to their short lasing pulse duration, high peak power, and beam quality in combination with the elements small size, are relevant for the ranging, telecommunications, space technology, industry, and medicine. ....
Solid-State Light Converters Optimized for High-Power LED Systems Written by AZoOpticsJan 27 2021 Materials scientists from Far Eastern Federal University (FEFU) worked with an international team of researchers team to optimize the design of composite ceramic materials (Ce 3+:YAG-Al 3), that is, solid-state light converters (phosphors) that can be employed in-ground and aerospace technologies.

The LED systems based on the developed materials to save 20-30 percent more energy compared to commercial analogues. A related article was published in Materials Characterization. Over 15% of the total global electricity production or about $ 450 billion annually spent on lighting. According to the photonics development roadmap run in Russia, the development of LED technology with an efficiency of more than 150 lm/W will allow to release up to 30% of electricity by 2025. ....
