摘要:

在频率调制光谱实验中,利用单频半导体激光器的辐射,在跃迁$B^3Π_{0_u^{+}}-X^1Σ^+_{g}$上记录了分子碘超精细结构在640 nm附近的光谱。由调制频率的值(在给定实验中为12.5MHz)给出的频率参考允许在仅使用一个激光器的实验中使用拟合过程以优于0.1MHz的精度确定超精细分量之间的频率差。

英文摘要:

In a frequency-modulation spectroscopy experiment, using the radiation from a single frequency diode laser, the spectra of molecular iodine hyperfine structure near 640 nm were recorded on the transition $B^3Π_{0_u^{+}}-X^1Σ^+_{g}$. The frequency reference given by the value of the modulation frequency (12.5 MHz in given experiment) allows determination of the frequency differences between hyperfine components with accuracy better than 0.1 MHz using the fitting procedure in experiment with only one laser.
