Abstract

Nowadays, quantum sensors are an interesting achievement combining high level physics with sophisticated technology. Scientists conduct more and more experiments with such sensors in space, using laser techniques. One of the them is the Doppler-free saturated absorption spectroscopy, that allows for great frequency stabilization. The aim of this thesis is to present an analysis and 3D design of a module, that achieves stabilization, using the aforementioned spectroscopic method, while having low cost and small size at the same time. The analysis includes the trade-off of the optical components that are going to be used, so that the most suitable combination is chosen, based on size, reflectivity, transmittance, wavelength range, manufacturer and price criteria, among others. In addition, a significant part of the analysis is dedicated to the intensity ratio of the two beams (pump-probe), both at the detector, and the atom cell. This way, one can choose the proper lenses and non-polarizing elements, that affect the final beam ratio. A testing version is built to prove that the spectroscopy configuration actually works, and the desired signal is presented. The preliminary design is included with the most important features, as created in Inventor (Autodesk 2021). At a later stage, it is to be used for the manufacturing of the final module, through the 3D printing technique.
