Nd:YAG晶体的光谱测试及其新波长激光
Abstract:
采用提拉法生长了掺Nd3+量为1.2%(摩尔分数)的Nd3+Y3Al5O12(NdYAG)激光晶体。测定了NdYAG晶体室温下300～3000nm的吸收光谱和808nm激光激发的荧光光谱,核定了Stark能级的位置。结果表明NdYAG晶体产生的1.3μm波长激光适用于光通讯,并具有人眼安全,对大气吸收低等特点,可用于激光雷达和和外科手术。4F3/2→4I9/2跃迁的946nm激光,倍频后产生的473nm蓝色激光,在激光存储和光显示方面有重要应用。4F3/2→4I11/2跃迁的1122nm激光倍频后可产生561nm黄色激光,可用作生物显微镜光源。
