In the past years, the fundamental research on atomic vapor quantum (sensing) systems made huge progress. With rising request of industrial applications for those systems, the demand for a production of high purity atomic vapor cells has increased. Although the used alkali metals (e.g. rubidium) are cheap and easily available, most of those quantum systems require purified isotopes for better control and higher sensitivity. The purification methods for isotopes are mostly inefficient and expensive, which limits the availability of enriched alkali isotopes on the market. This affects the cost and the advance from the transfer of scientific knowledge to industrial applications. To overcome this limitations, we propose an apparatus for the in–atomic–vapor–cells enrichment of rubidium isotopes using lasers, which can be used for the production of purified vapor cells from the natural abundance of the isotopes on. Combined with an outstanding collection efficiency, this could serve as a sustainer for the development of industrial applications using atomic vapor cells.
