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.
The spectral structure of 511nm and 578nm spontaneous transitions of Cu atoms were calculated by considering the fine structure of energy level and isotope splitting, etc. The CuBr laser with buffer gas-sealed operation was designed and fabricated, and the effect of neon gas at low pressure The spectral structures of the 511 and 578 nm laser lines of the buffer gas CuBr laser at different operating temperatures and excitation voltages show that the spontaneous emission spectra and laser spectra of the 511 and 578 nm lines have similar multimodal structures. However, the 578 nm laser The spectral line is closely related to the operating temperature and excitation voltage, and qualitative analysis of the experimental results.
