Abstract

Using the Czochralski method, Er$_2$O$_3$ doped near stoichiometric LiNbO$_3$ single crystals were grown 15~20 mm in diameter and 30-35 mm in length for Z-axis. Lattice constants were inspected by the X-Ray Diffractometer (XRD) and through Fourier Transform-Infrared Spectrophotometer (FT-IR), it observed absorption band. Also, the distributions of Er concentration were confirmed by the Electron Probe Micro Analysis (EPMA).

Czochralski법을 이용하여 Er$_2$O$_3$가 첨가된 near stoichiometric조성의 LiNbO$_3$ 단결정을 Z-축의 방향으로 직경 15~20mm, 길이 25-30 mm의 크기로 성장시켰다. X-Ray Diffractometer (XRD)을 이용하여 격자상수를 조사하였고, Fourier Transform-Infrared Spectrophotometer (FT-IR)을 통하여 흡수밴드를 관찰하였다. 또한 Electron Probe Micro Analysis (EPMA)를 이용하여 결정 내에 Er의 분포를 확인하였다.
