Highly efficient poly crystalline Nd:YAG ceramic laser

摘要

Highly efficient Nd:YAG ceramic laser at 1064 nm was demonstrated. Using 1 W LD end-pumping scheme, with 883 mW pumping, 499 mW 1064 nm CW laser output has been obtained corresponding to an optical to optical efficiency of 56.5 percent. High power CW Nd :YAG ceramic rod laser was also demonstrated. The maximum output power of 62.5 W with was obtained at 1064 nm. The optical to optical conversion efficiency is 21.6 percent.
