Trapping and cooling of atomic strontium in a compact apparatus : Towards a micro ring cavity QED experiment

In the past few years, the emergence of an ensemble of quantum entanglement based technologies have defined a Second Quantum Revolution. Atomic ensembles with alkaline-earth-like species as strontium and ytterbium posses promising long-lived quantum states for these technologies. Among the physical platforms allowing to generate entanglement, cavity quantum electrodynamics is particularly interesting. In this spirit, we aim to develop an experiment combining ultra-cold strontium atoms and a miniaturized ring cavity. This thesis is dedicated to the description of the laser and vacuum systems used to generate cold strontium samples on two optical transitions at 461 and 689nm, as well as a characterization of the obtained atomic clouds.
