Progress in research and application of transparent Nd:YAG laser ceramics

The paper reviews the recent worldwide research and application of transparent Nd:YAG laser ceramics, especially in the last two years, and focuses on the analysis of the recent research in China. It points out that the transparent Nd:YAG laser ceramic is the current focus in ceramic research. At last, it puts forward the research difficulties and points out that the research in China is still far behind the world level. In conclusion, the colleges and institutes of material and optics in China, should cooperate on theory and progressing of the transparent Nd:YAG ceramics.
