Abstract

We describe a saturated absorption setup that is robust, compact and require minimum alignment. These properties are attained using a diffuse probe beam generated by a retro-reflecting film. This concept was studied and applied to built a miniaturized setup that had shown the same performance than an optimized table-top experiment.
