【Abstract】 The growth defects of LBO crystals were investigated by methods of optical micrography and white_beam synchrotron radiation topography (WBSRT). The results indicate that the main defects in LBO crystal are dislocation, inclusion and sector boundary. The causes of forming the defects and the measures for improving the quality of crystals have been discussed.更多还原
