This paper investigates the scattering effect of domestic 0.5 at% ceramic Nd：YAG. An effective method has been utilized to measure the scattering and absorption coefficients. An end-pumped continuous wave （CW） Nd：YAG ceramic laser was also demonstrated. A maximum output power of 6.7 W at 1064 nm was obtained at an 808-nm pump power of 32.9 W. Conversion efficiency and slope efficiency have been achieved. This indicates that scattering has an important effect on the optical performance of ceramic Nd：YAG.
