  • 报道了观察到的碘分子(127I2)在633nm波段的5组超精细强谱线,并对每组谱线的频率间距及相应振转能级的跃迁强度作出了计算,结果和实验吻合得很好.利用计算结果,对这5组谱线对应的振转能带作出了甄别.由于这些新谱线比用于氦氖激光器稳频的R(127)11.5跃迁强几百倍,因此利用这些新谱线作为半导体激光稳频的参考谱线,得到了功率为3mW的激光输出,这种半导体激光可成为新型光频标.
    In this paper, five groups of stronger hyperfine transitions of iodine molecule (127I2) are reported, which are to our knowledge first observed by us. Frequency separations and relative intensities of each transition are calculated. The calculated results and the observed values match very well. With the calculated results, we assigned the vib-rotational bands of each transition. Because the intensities of the newly observed transitions are hundreds of times stronger than transition R(127)11-5, which is applied to frequency-stabilized He-Ne laser, we use them as reference lines of iodine frequency stabilized tunable diode laser and get an output laser 3mW. This kind of frequency-stabilized diode laser may become a new kind of frequency standard.
