Abstract:
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.
