Abstract

Potassium lithium niobate doped with CeO₂ and CuO, Ce:Cu:KLN crystals were grown by Czchralski method for the first time. The exponential gain coefficient of KLN and Ce:Cu:KLN crystals were measured. Effective charge densities of those crystals were computed. The exponential gain coefficient of KLN and Ce:Cu:KLN crystals are 7.4cm^-1 and 4.1cm^-1. The effective charge density exponential gain coefficient of KLN and Ce:Cu:KLN crystals are 3.2×10²²/m³ and 4.2×10²²/m³. The IR transmission spectra of KLN and Ce:Cu:KLN crystals were measured. OH- absorption peak of Ce:Cu:KLN shift red compare to that of KLN. The Raman spectra of those crystals were measured. The Raman spectra of KLN and Ce:Cu:KLN crystals were basically alike, which justified the fact that the ions of impurities entered into the lattice by replacement of original ions of KLN crystals.
