摘　　要：一、前言 已获得广泛应用的铝酸盐激光晶体,如YAG:Nd^(3+)、YAP:Nd^(3+)有许多优点,但它们的Nd^(3+)离子发光浓度粹灭效应严重,限制了掺杂浓度。YAG:Nd^(3+)只能掺入约2×10^(20)/cm^3。为了探索高Nd^3+)浓度的激光晶体,法国科学家在1981年制备了LaNdMgAl_(11)O_(19)晶体。我们用提拉法生长了LNA单晶,测量了77K和300K的吸收谱、荧光及偏振荧光谱和荧光寿命,并获得了57mJ的1.054/,m的脉冲激光输出。The spectroseopie nd lasing properties of Nd3+ in LaMgAl11O19 crystals were investigated experimentally. The absorption spectrum, fluorescence, polarization spectrum and fluorescence lifetime were measured. An advantage is that the concentration quenching of Nd3+ luminescence is quite weak, and the doping concentretion can be up to a higher value. Laser output has been obtained from the crystal at 1.054μm.
