“…At present, this branch of the research and development of LDpumped crystalline lasers continues to grow very fast (see, e.g. [7][8][9] [10]), makes it possible to obtain these laser ceramics with any required size and activator ion concentration, which correspondingly has allowed the achievement of multi-kilowatt levels of continuous wave (CW) Y 3 Al 5 O 12 :Nd 3+ laser output power with LD pumping at the one-micron lasing channel ( 4 F 3/2 → 4 I 11/2 ) during the last several years [12,13]. The extremely active interest in the study of nonlinear optical cascaded effects in χ (3) -and (χ (2) + χ (3) )-active crystalline materials can be accounted for by a number of practical reasons.…”

After a brief examination of known insulating laser crystals and the stimulated emission channels of their generating activator ions, this article reviews recent advances in the development of novel lasing crystals and ceramics, as well as inorganic and organic nonlinear-laser crystals for χ (3) and cascaded χ (3) ↔ χ (2) frequency converters. Several new modern attractive technologies in the physics and techniques of crystalline lasers are also discussed.Section of the crystal structure of Na3Li (SeO4)

Transparent Ce:YAG ceramics were fabricated by the solid-state reaction method with an additional round of pre-calcining using nanopowders of Ce 2x Y 2−2x O 3 (x = 0.001, 0.01, 0.03 and 0.05) and Al 2 O 3 synthesized by laser ablation. Additional pre-calcining of the nanopowder mixture in air was used to partially transform the oxides into the YAG phase before sintering. The transmittance of the obtained 2-mm-thick Ce:YAG ceramics was over 81 % in the wavelength range of 500-900 nm. The average volumes of the scattering centers in the obtained ceramics were evaluated by direct count method to be 34, 74, 53, 50 ppm for 0.1, 1, 3 and 5 % Ce doping concentration, respectively. The absolute light yields, energy resolutions under 662 keV gamma ray, and decay curves of scintillations of the fabricated Ce:YAG samples were measured and compared to those of Ce:YAG and CsI:Tl single crystals.

“…Thus, special measures were adopted during precipitation, such as addition of surfactant to create non-agglomerated nanoparticles. It is reported that the surfactant (NH 4 ) 2 SO 4 , which adsorbs on the surface of the Y(OH) 3 , hinders the bonding between particles [5,6]. It has also been shown that the morphology of precursors was affected by the [(NH 4 ) 2 SO 4 ]/[Nd:Y 2 O 3 ] ratio (measured by weight) [7].…”

Nanoparticles of Yb:Y 2 O 3 have been synthesized by co-precipitation synthesis routes. The (NH 4 ) 2 SO 4 surfactant was added to Y(OH) 3 precipitate during synthesis to control the size, morphology, agglomeration and phase of nanoparticles. The dried precipitates were calcined at 900 • C to obtain the desired cubic phase Yb:Y 2 O 3 nano particles. In the present study we reported the effects of surfactant concentration on size, morphology, agglomeration and phase of Yb:Y 2 O 3 nanoparticles. However the addition of surfactant is not enough to get nonagglomerated nanoparticles. The extracted precipitate should be washed in proper solvent to avoid formation of hard agglomerate during drying. Hence the effects of washing solvent (i.e. water and methanol) on agglomeration and transparency were also reported. The transparency of the sintered pellets, prepared by varying the surfactant concentration and washing solvent, was evaluated. A transparency of ∼ 80 % at 1500 nm was achieved in 1 mm thick Yb:Y 2 O 3 ceramic pellet by optimization of the surfactant and washing solvent.
