摘要： 采用熔盐法生长出尺寸为30mm的Nd3+:GdAl3(BO3)4优质晶体,进行了吸收光谱和荧光光谱的测定研究,计算得到晶体发射截面为σe1061.9=2.9×10-19cm2和σe1338mm=5.5×10-20cm2.采用染料激光器作为泵浦源,对晶体进行了自变频激光实验研究,在紫外可调谐(378-382nm)、绿光531nm、蓝光(436-443nm)、红光(669nm)和红外可调谐(1305-1365nm)波段实现了激光输出,输出的最大功率分别为:105μJ/脉冲、119.5μJ/脉冲、445μJ/脉冲、19μJ/脉冲和31μJ/脉冲.

Abstract: Nd3+:GdAl3(BO3)4 crystals with the size up to 30mm were grown by using the flux method. The absorption and emission spectra in function of the
σ and π polarizations were presented. The radiative lifetime of the 4F3/2 level is 293\mus. From the Judd-Ofelt parameters, the σ-polarized
stimulated emission cross-section was measured to be 2.9×10-19cm2 at the laser wavelength: 1062.9nm, and 5.5×10-20cm2 at the laser wavelength:
1338nm. UV generation tuneable in 378～382nm , green(531nm) generation, blue generation tuneable in 436～443nm and red(669nm) generation as well as infrared
generation tuneable in 1305～1365nm by self-frequency changing were obtained with the output of 105μJ/pulse, 119.5μJ/pulse, 445μJ/pulse, 19μJ/pulse
and 31μJ/pulse respectively, when this crystal was pumped by dye laser.
