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

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
The transmissivity and the results of two-beam coupling and self-pumped phase conjugation (SPPC) experiments on Co-doped potassium sodium strontium barium niobate (KNSBN) single crystals are reported. The Co ions doped into KNSBN can form a deep energy level near 2.25 eV. The two-beam coupling gain
## Abstract Alkali metals (Na, Rb or Cs) coβdoped with fiberβ and bulkβshaped KNbO~3~ single crystals were grown using two original methods by means of doping together of small ionic Na and large ionic Rb or Cs into KNbO~3~. Singleβphase crystals could be grown with an orthorhombic system at room t
