摘要
The study on the growth, laser performances and the relationship between the lumine-scence concentration quenching effect vs. the composition and the structural charac-teristics of neodymium aluminium borate （NAB NdAl<sub>3</sub>（BO<sub>3</sub>）<sub>4</sub>） is reported. By introducingthe atomic parameter L, the difference in luminescence concentration effect of active ionsNd<sup>3+</sup> in different host crystals with various chemical compositions can be well described.The rationality of the introduction of this parameter is discussed theoretically. A pulsedlaser energy of 1205 mJ at 1.063μm has been obtained. The 1.34-μm pulsed laser and thesecond harmonic generation of 1.063μm laser experiments are studied. The laser energyoutputs at 1.34μm and 0.532μm were measured to be 49 mJ and 25.5 mJ.
