We describe a saturated absorption spectrometer that is robust and compact and requires minimum alignment, which is made possible by using a diffuse probe beam generated by a retro-reflecting film. This concept was studied and implemented in a miniaturized home-built setup that provides the same performance as an optimized table-top setup.

小型化饱和吸收光谱仪

我们描述了一种饱和吸收光谱仪，它坚固而紧凑，需要最少的对准，这可以通过使用由回射膜产生的漫射探测光束来实现。这个概念是在小型化的自制设置中研究和实施的，该设置提供与优化的桌面设置相同的性能。
