“…For, example annealing the 2 at % Nd:Y 2 O 3 powder at 1200ºC increased the lifetime to ~190 µs. Overall, the obtained Nd:Y 2 O 3 powders exhibited shorter emission lifetimes then that `reported for Nd:Y 2 O 3 bulk crystals (~300 µs) [11].…”

“…1 at.% and 2 at.% Nd:Y 2 O 3 powders samples showed intense Nd 3+ emission lines in the ~900-1000 nm range ( 4 F 3/2 -> 4 I 9/2 ), ~1050-1150 nm ( 4 F 3/2 -> 4 I 11/2 ), and ~1300-1450 nm ( 4 F 3/2 -> 4 I 13/2 ) (see Fig. 4) [6,11]. The linewidth of the emission features was limited by the resolution of the emission setup.…”

“…Neodymium doped Yttria (Nd:Y 2 O 3 ) is another material that has attracted considerable attention due to its lasing wavelengths and excellent thermo-mechanical properties [6][7][8][9][10][11]. The specific Stark level splittings in Nd:Y 2 O 3 provides two emission lines at 914 nm and 946 nm originating from the 4 F 3/2 → 4 I 9/2 transition.…”

“…It has emission cross-sections approaching those in Nd:YAG, and it has the smallest 1.06μm/0.94μm cross-section ratio of any Nd doped material commonly known. All of these characteristics make Nd:Y 2 O 3 an excellent candidate for study toward applications for atmospheric ozone DIAL measurements [11].…”

“…The cubic Y 2 O 3 single crystal has several favorable properties such as a refractory nature, stability, and optical clarity over a broad spectral range [5][6][7][8][9][10][11]. Furthermore, the thermal conductivity and thermal expansion coefficients are very similar to those of YAG.…”

Solid-state lasers play a significant role in providing the technology necessary for active remote sensing of the atmosphere. Neodymium doped yttria (Nd:Y 2 O 3 ) is considered to be an attractive material due to its possible lasing wavelengths of ~914 nm and ~946 nm for ozone profiling. These wavelengths when frequency tripled can generate UV light at ~305 nm and ~315 nm, which is particularly useful for ozone sensing using differential absorption lidar technique. For practical realization of space based UV transmitter technology, ceramic Nd:Y 2 O 3 material is considered to possess great potential. A plasma melting and quenching method has been developed to produce Nd 3+ doped powders for consolidation into Nd:Y 2 O 3 ceramic laser materials. This far-from-equilibrium processing methodology allows higher levels of rare earth doping than can be achieved by equilibrium methods. The method comprises of two main steps: (a) plasma melting and quenching to generate dense, and homogeneous doped metastable powders, (b) pressure assisted consolidation of these powders by hot isostatic pressing to make dense nanocomposite ceramics. Using this process, several 1" x 1" ceramic cylinders have been produced. The infrared transmission of undoped Y 2 O 3 ceramics was as high as ~75% without anti-reflection coating. In the case of Nd:Y 2 O 3 ceramics infrared transmission values of ~50% were achieved. Furthermore, Nd:Y 2 O 3 samples with dopant concentrations of up to ~2 at. % were prepared without significant emission quenching.

Transparent ceramics of the formula (Nd 0.01 La x Y 0.99−x ) 2 O 3 (x = 0, 0.05, 0.10) were made with nanopowders and sintered in H 2 atmosphere. The Raman spectra of Ln 2 O 3 (Ln = Y, La, Nd) powders and (Nd 0.01 La x Y 0.99−x ) 2 O 3 ceramics were investigated. The results show that both La 2 O 3 and Nd 2 O 3 powders are of hexagonal structure, and all (Nd 0.01 La x Y 0.99−x ) 2 O 3 ceramics exhibit the same cubic Y 2 O 3 crystal structure. Their lattice parameters were refined by the Rietveld method. The full-widths at half-maximum of Raman peaks increase with the increase in La 2 O 3 content in transparent (Nd 0.01 Y 0.99 ) 2 O 3 ceramics, while their intensities decrease. At the same time, All Raman peaks shift to lower wavenumbers, and the phonon energy is slightly reduced.

Observation of nonlinear lasing χ⁽³⁾-effects in highly transparent nanocrystalline Y₂O₃ and Y₃Al₃O₁₂ ceramics

Multi-wavelength nonlinear parametric χ (3) -effects were observed in highly transparent Y 2 O 3 and Y 3 Al 5 O 12 nanocrystalline ceramics under picosecond pumping at 300 K. All recorded Stokes and anti-Stokes components in the visible and near IR were identified and attributed to the stimulated Raman scattering active vibration modes of these novel optical and laser-host crystalline materials. For both materials, the steadystate first-Stokes Raman gain coefficient was estimated at a wavelength of around 1 µm.
