| Abstract(in English) | Optical properties including optical absorption, emission spectra and fluorescence lifetime have been investigated for polycrystalline Nd-doped Y_3Al_5O_<12>(Nd : YAG)ceramics. Very similar results were obtained with that of Nd : YAG single crystals. Highly efficient Nd : YAG ceramic laser at 1064nm was demonstrated. Using 1 W LD end-pumping scheme, with 883mW pumping, 499mW 1064nm CW laser output has been obtained corresponding to an optical to optical efficiency of 56.5%. High power CW Nd : YAG ceramic rod laser was also demonstrated for the first time. The maximum output power of 31 W with 18.8% slope efficiency was obtained at 1064 nm. The potential of Nd : YAG ceramic laser was also discussed. |
