AI 中文摘要
我们对空心阴极灯中银原子在$5{^{2}}\text{S}_{1/2} \rightarrow 5{^{2}}\text{P}_{3/2}$跃迁上的激光吸收开展定量研究。测量弱探针获得的光谱，并与简单理论模型对比；拟合结果以提取灯内银原子的有效温度和数密度，确认光谱由多普勒展宽主导。我们分析银与灯内氖缓冲气体碰撞的展宽效应，证实该效应虽小，但会改变模型的最优有效参数。本研究得到了适用于该灯内激光吸收的简单、定量且可预测的模型。
英文摘要
We present a quantitative study of laser absorption on the $5{^{2}}\mathrm{S}_{1/2} \rightarrow 5{^{2}}\mathrm{P}_{3/2}$ transition of silver in a hollow-cathode lamp. Spectra obtained using a weak probe are measured and compared to a simple theoretical model. We fit our results to extract an effective temperature and number density associated with the silver in the lamp and confirm that the spectra are dominated by Doppler broadening. We consider the broadening effect of collisions between silver and the neon buffer gas in the lamp, and establish that these effects are small but modify the optimum effective parameters for the model. Our work results in a simple, quantitative, and predictive model for laser absorption in the lamp.
