Synthesis, Optical Absorption, and Site-Selective Excitation of the 3P0 Levels in Y4Al2O9:Pr3+

Autor: O.K. Moune, Y. Rabinovitch, D. Tetard, M.D. Faucher

Publikováno v: The Journal of Physical Chemistry A. 108:8244-8255

Y4Al2O9:Pr3+ was prepared by two methods: starting from the citrates and direct sintering of the oxides. The latter method gave more single-phased samples. Optical spectroscopy was utilized to obtain the emission spectra from the individual sites of

Transparent polycrystalline neodymium doped YAG: synthesis parameters, laser efficiency

Autor: M. Pham-Thi, M.D. Faucher, D. Tétard, Y. Rabinovitch

Publikováno v: Optical Materials. 24:345-351

Two synthesis techniques to produce transparent Nd:YAG ceramics were investigated. The most transparent were obtained by the sintering of commercial oxides. The spectroscopic analysis reveals very similar properties to that of single crystals. In a l

A spectroscopic investigation of Y 3 Al 5 O 12 :Pr 3 + in translucent ceramic form: Crystal field analysis assisted by configuration-interaction

Autor: M.D. Faucher, Y. Rabinovitch, O.K. Moune, D. Tétard, M. Pham-Thi, E. Lallier

Publikováno v: The European Physical Journal D - Atomic, Molecular and Optical Physics. 19:275-291

This paper presents an investigation of Pr3+ doped in the D2 site of Y3Al5O12 (YAG), for the first time on a translucent ceramic sample free of spurious phases, impurity or pair sites. The optical study is carried out by optical absorption, excitatio

Ceramic processes applied to amplifier media for high power lasers: potentialities and limits

Autor: Y. Rabinovitch, Sallé Christian, Alexandre Maitre, Rémy Boulesteix

Publikováno v: Advanced Solid-State Lasers Congress.

This study shows that a perfect control of each steps of the elaboration process (powder synthesis, shaping and sintering) is needed to avoid defects affecting the transparency of Nd:YAG ceramics developed for high power laser applications.

Freeze-dried nanometric neodymium-doped YAG powders for transparent ceramics

Autor: Hichem Dammak, Fabienne Karolak, Christine Bogicevic, D. Tetard, Y. Rabinovitch

Publikováno v: Journal of Materials Processing Technology
Journal of Materials Processing Technology, Elsevier, 2008, 199, pp.314-320. ⟨10.1016/j.jmatprotec.2007.08.022⟩

Nanometric neodymium-doped yttrium aluminium garnet (YAG) has been synthesised from freeze-dried precursors. The products were calcined between 900 °C and 1200 °C under flowing oxygen. Powder morphologies were observed by TEM, SEM and laser granulo
