✦ Synopsis

Single LiNbO 3 :Tm 3+ crystals, with variable Tm 3+ content, have been grown by using the Czochralski method. The incorporation of Tm 3+ ions into LiNbO 3 crystals has been determined by using X-ray fluorescence spectroscopy. At moderated doping levels the active ion incorporation is driven by a linear regime, with a segregation coefficient K eff = 1.19 ± 0.08. Saturation effects have been observed only for highly concentrated crystals. The absorption spectra of Tm 3+ -doped crystals indicate that the melt congruent composition is preserved within the crystals. The Tm 3+ absolute absorption cross sections have been obtained.

Single crystals of lithium niobate doped with 0.03 and 0.1 at.% of Cu or Fe ions were grown by the Czochralski technique. Optical absorption spectra in visible and infrared regions before and after γ irradiation with doses up to 10 5 Gy were measured and positions of both dopants in LiNbO 3 lattice
