英文摘要：

As a new generation of solid state laser gain media, Nd ： YAG ceramics are now gradually substituting their single crystal or glass counterparts, owing to its advantages such as easy fabricated, cost-effectiveness and flexibility in fabricating with large size, etc. It has very considerable application prospect. In this paper, from three aspects including optical quality optimization of Nd ： YAG transparent ceramics, laser characteristic and the achievement of high power Nd ： YAG ceramic laser output, the research progress of Nd ： YAG transparent ceramics in China, Japan, America, Europe and Russia are introduced, respectively. The development of composite as well as co-doped Nd ~ YAG ceramics in China and Japan are also introduced. Finally, the tendency and the main hinders for the development of transparent Nd ： YAG ceramics are summarized.
