Abstract

For growing single crystals of lithium tantalate of optical quality with high homogeneity of their composition and desired concentration of dopant of samarium a method for producing a solid precursor Ta2O5⟨Sm⟩ and homogeneously doped charge LiTaO3⟨Sm⟩ of a congruent composition was developed. X-ray diffraction analysis and IR spectroscopy were used to study the phase composition of Ta2O5⟨Sm⟩ and LiTaO3⟨Sm⟩. Conditions for preparation of the monophasic charge LiTaO3⟨Sm⟩ were determined: (Sm concentration in Ta2O5 ≤ 1.5 wt %, the molar ratio [Li2O]/[Ta2O5] = 0.941, synthesis temperature 1200°C). By mass spectrometry with inductively coupled plasma and sampling by laser ablation a distribution of the dopant of samarium in Ta2O5⟨Sm⟩ and LiTaO3⟨Sm⟩ was examined and the chemical homogeneity of the synthesized products was confirmed.
