Investigation on the scattering effect of ceramic Nd:YAG

doi:10.1088/1674-1056/19/6/064202

Abstract 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.

Keywords: Nd:YAG transparent ceramic light scattering optical-to-optical efficiency
