Abstract
Periodic poled lithium niobate crystals have been prepared by the Czochralski technique using a non-symmetrical temperature field. Er and Yb ions have been added to the melt in different concentrations and its effect on the formation of the periodical structures has been studied. The periodical domain structures are improved for dopant concentrations lower than the solubility limit. The formation of the periodical domain structures is related with the dopant segregation coefficient value and with the temperature gradient in the interface.
