| 英文摘要 | High-quality 1.3at% neodymium-doped yttrium aluminum garnet (nd:yag) transparent ceramic was fabricated by a solid-state reaction method and vacuum sintering using high-purity alpha-al2o3, y2o3 and nd2o3 as raw materials with tetraethoxysilane (teos) as sintering aid. the microstructure, the spectral property and the laser performance of the prepared nd:yag ceramic were studied. it is found that the sample exhibits pore-free structure with average grain size of 15 mu m. there is no secondary phase in the grain boundary and grain. transmittance of the sample after annealing reaches 82.4% at the laser wavelength of 1064nm. the highest absorption peak is centered at 808.6mn and the absorption coefficient is 4.45cm(-1). the peak absorption coefficient at laser wavelength of 1064mn is 0.11cm(-1). the fwhm of 1064nm main emission peak is 0.82nm, and the fluorescence lifetime is 258 mu s. a laser diode (808nm) was used as pump source whose maximium output was 1000mw, and end-pumped laser experiment was demonstrated on 1.3at%nd:yag ceramic. the sample for laser testing is phi 16mm x 2.8mm in dimension, mirror-polished on both sides and without coating. with 731 mw of. maximum absorbed pump power, laser output of 45mw is obtained with slope efficiency of 23.2%. the laser threshold is 530mw. |
