Keywords： spectrum properties , Czochralski method , high average power solid state laser (HAP SSL) , laser crystal , Nd3+:GGG

用提拉法生长了掺钕的钆镓石榴石(Nd3+:GG)激光晶体.研究了室温下的吸收光谱和荧光光谱性质,分析了Nd3+:GG晶体4F3/2→4I11/2能级跃迁与1.06μm附近的荧光谱线之间的关系.吸收系数、发射系数、荧光寿命分别是4.32×10-20 cm-2,2.3×10-19cm-2, 240μs, 比较了Nd3+∶GGG 和 Nd3+∶YAG 的物理参数,实验表明:d3+∶GGG较Nd3+∶YAG有一系列的优点.

The HAP SSL crystal Nd3+:d3Ga5O12(Nd3+:GG) was grown by the Czochralski method. The absorption and emission spectra of Nd3+:GG crystal at room temperature were studied. The relationship between the energy level scheme and the emission spectra was analyzed. The absorption, emission cross-section and fluorescence lifetime are estimated as 4.32×10-20cm-2,2.3×10-19cm-2, 240μs, respectively. From the oscillator strengths of the absorption transitions the Judd-offelt intensity parameters were evaluated.The spectroscopic parameters of Nd3+:GG and Nd3+:AG crystal were compared, and the Nd3+:GG crystal has many advantages over Nd3+:YAG.
