这封信描述了饱和吸收光谱到诊断应用的空间分辨（点）吸收测量的扩展。该技术通过使用交叉光束而不是反向传播饱和光束和探测光束来修改无多普勒饱和光谱的标准配置。该方法通过对从盐溶液中吸入的原子钠进入大气压氢气-空气火焰中的分布的研究得到了证明。其他两束无多普勒光谱方法的类似改编可用于提供空间分辨测量技术。
This Letter describes the extension of saturated absorption spectroscopy to spatially resolved (point) absorption measurements for diagnostic applications. The technique modifies the standard configuration of Doppler-free saturation spectroscopy by using crossed, rather than counterpropagating, saturating and probe beams. The method is demonstrated in a study of the distribution of atomic sodium aspirated from a salt solution into an atmospheric-pressure hydrogen-air flame. Similar adaptations of other two-beam Doppler-free spectroscopic methods can be used to provide spatially resolved measurement techniques.
