Raman scattering and luminescence of the Nd{sup 3+}-ion crystal-field excitations in Nd{sub 2}O{sub 3} single crystal and polycrystalline powder are studied as a function of temperature and magnetic field. Splitting of Kramers doublets due to Nd{sup

Yttrium oxide plasma-spray deposits show a metastable B phase together with the cubic stable form. This B form is prejudicial for thermal applications of these coatings (i.e. weakens mechanical properties, etc.). Attempts have been made to avoid the

Yttrium oxide coatings were obtained by plasma spray. Structural investigations on these deposits show that, due to the drastic conditions of this technique, a minor monoclinic B phase is formed in the neighborhood of the major cubic C form. We discu

This paper reviews our work on the Yb:Er:Cla2Al2SiO7 (CAS) laser material. Absorption and emission properties are reported. A high value of the Yb → Er energy transfer rate (6x10^-16 cm³s-1) is favourable to the broad Er3+ near infrared emission.

In recent years, considerable interest has been devoted to the laser emitting in the 1.5–2 μm range. Ho3+ and Tm3+ operate around 2 μm while Er3+ covers the 1.5 μm range. The development of high power laser diodes lasing around 0.78 and 0.98 μm

In an effort to improve some of the performances of γ LiAlO2 possibilities of modifications in the crystal lattice of this compound have been studied. To this end, substitutions of aluminum and/or lithium ions were made with various elements resulti

Refractive-index dispersion and anisotropy were measured in tetragonal Ca2Ga2SiO7 (CGSM; Ga-gehlenite) and SrLaGa3O7 (SLGM) single crystals at room temperature between 308 and 1064 nm. Large single crystals were grown by the Czochralski method. Biref
