采用熔盐提拉法生长出φ20min×35mm的优质Nd~(3+):KGd(WO_4)_2晶体,对晶体三个轴向的光谱进行了测试研究,结果表明a轴向的吸收和荧光谱峰最强,最适合于进行激光实验研究.采用脉冲氙灯泵浦φ3.5mm×26mm的激光器件,在1.067μm处得到125.5mJ的激光输出.在同等条件下对YAG:Nd激光晶体进行了激光实验研究,并对两种结果进行了比较,结果表明:和YAG:Nd~(3+)晶体相比,KGW:Nd~(3+)晶体具有激光阈值低、效率高和输出光为偏振光等优点,因此在小型激光器的应用方面具有明显的优势. The crystal structure of Nd3 +: KGd (WO4) 2 crystal with diameter of 20 mm × 35 mm was grown by molten salt pulling method. The results show that the absorption and fluorescence spectra of a axis The strongest peak, the most suitable for laser experimental study using a pulsed xenon lamp pumped φ3.5mm × 26mm laser device, obtained at a laser output of 125.5mJ at 1.067μm YAG: Nd laser crystal under the same conditions were laser The experimental results show that KGW: Nd ~ (3 +) crystal has low laser threshold, high efficiency and polarized light as compared with YAG: Nd ~ (3 +) crystal And other advantages, so the application of small lasers has obvious advantages.
