摘　　要：综合考虑能级精细结构和同位素分裂等因素,计算了铜原子511nm和578nm自发跃迁谱线的光谱结构.设计制作了可周期更换缓冲气体封闭运转的CuBr激光器,测量了低气压下以氖气为缓冲气体的CuBr激光器的511nm和578nm激光谱线在不同工作温度和激励电压时的光谱结构.结果表明铜原子511nm和578nm谱线的自发辐射光谱和激光光谱具有类似的多峰结构,但578nm激光光谱线形与工作温度和激励电压密切相关,对实验结果做了定性分析.Under consideration of the basic factors such as the level hyperfine structure and isotope split etc., the spectral structures of spontaneous emission of copper atom 578/511 nm lines are calculated. A sealed operation CuBr laser with periodical refreshment of the buffer gas are designed and constructed. The 578/511 nm spectral structures, produced by CuBr laser at lower Ne buffer gas pressure were measured under different working temperatures and exciting voltages. The spectral structure of spontaneous emission of copper atom 578/511 nm lines have multi-peaks similar to their laser spectral structure, but the 578 nm laser line is strongly dependent on the working temperature and the exciting voltage. Some possible reasons are suggested to qualitatively explain the experimental results.
