A new nanotechnology for the synthesis of highly transparent ceramics, including laser synthesis of nanopowders, their compaction and vacuum sintering of compacts. It differs from the known use of weakly agglomerated nanopowders with a smaller particle size and static compaction with ultrasonic action on the nanopowder. This makes it possible to synthesize high-transparent ceramics of large size at lower sintering temperatures.

The installation and technique of uniaxial static pressing with ultrasonic action on a nanopowder is developed.

The modes of sintering of compacts are investigated and the reasons for the formation of additional phases and conditions for the synthesis of single-phase ceramics are revealed.

Samples of high-transparent ceramics of Nd:Y₂O₃ type, as well as new Lu:Y₂O₃, with disordered crystal structure, promising for the creation of femtosecond lasers, were synthesized.

In 2007, for the first time in our country after Japan and earlier than in other countries, the generation of domestic samples of Nd:Y₂O₃ ceramics at a wavelength of 1.07 µm with a differential efficiency of 15% was obtained.

A new magnetooptic material based on Tb₂O₃ with the highest transparency of 82.5% and the Verde coefficient of 120 rad/(Tl m) more than three times higher than the value realized in the Faraday insulator based on commercial terbium gallium garnet was synthesized.

For the first time on strongly disordered ceramics Yb(LuY)₂O₃ doped Zr the generation with efficiency more than 50% is received and the widest in the near IR range smooth tuning of frequency of radiation (~100 nm) was realized.

The methods of synthesis of YAG ceramics doped Nd, Yb, Ho and used as active elements of lasers with differential efficiency up to 52.7%, and when doping Ce as scintillators, were developed.

The method of synthesis of composite ceramics, as well as diffuse welding of highly transparent ceramics were developed.
