Abstract
Single crystals of LiNbO3:Er3+, LiNbO3:Tm3+, LiNbO3:Er3+ + Tm3+ and LiNbO3:Er3+ + Tm3+ + Mg2+ were grown by the Czochralski method starting from the congruently melting composition. Uniformly doped crystals were obtained at pulling rates 1 - 2 mm/h and rotation rates 5 - 20 rpm. The crystals were grown either in Y or in Z direction. The as-grown crystals were regular and free of macroscopic defects. The poling of crystals was carried out as a separate operation. Electrodiffusion was not observed during poling which was confirmed by x-ray microprobe analysis. The absorption spectra of Tm3+, Er3+ and Mg2+ doped LiNbO3 single crystals were studied in spectral range 2000 - 28,000 cm-1 at temperatures from 15 to 300 K. The interaction between Tm3+ and Er3+ ions resulting in changing of absorption spectra structure for particular terms related to Tm3+ and Er3+ ions has been observed.
