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 ฮณ irradiation with doses up to 10 5 Gy were measured and positions of both dopants in LiNbO 3 lattice
The elaboration of Yba+-doped LiNbO 3 : Sc 3+ and LiNbO 3 : Mg 2+ single crystal fibers by the laser heated pedestal growth technique is reported. The ytterbium emission and absorption cross-sections are given. We show that it is possible to obtain the coincidence between the wavelength of phase-mat
