Alkali metal (Na, Rb or Cs) ion doped KNbO 3 fiber single crystals are grown using an original pulling down method, to improve their composition change during a crystal growth, by means of co-doping of small ionic size Na and large ionic size Rb or Cs into KNbO 3 . In spite of the co-doping, single
Optical planar waveguides have been fabricated by the titanium in-diffusion process in lithium niobate crystals activated with erbium ions. The waveguides were studied by m-line technique in order to recover the index profile. The effect of the Ti in-diffusion on the structural and spectroscopic pro
Pure and Co-doped Li 2 B 4 O 7 (LBO) single crystals were grown by the Czochralski method. Starting concentrations of Co 2 O 3 in the melt were: 0.5, 0.85 and 1 mol% relative to Li 2 CO 3 . Technological factors affecting the quality of both crystals were discussed. Optical absorption and EPR spectr
High quality magnesium-doped potassium lithium niobate (designated as KLN:Mg) single crystal was grown for the first time. The tetragonal tungsten bronze structure of the Mg:KLN crystal was determined by X-ray powder diffraction, in which the lattice parameters were a=l.262um and c=0.398nm. High tem
