Laser system for the cooling and handling of ultra-cold strontium atoms

Operation co-funded by EU cohesion policy (European Regional Development Fund (ERDF)) under the programme Multi-regional Spain - ERDF (2014ES16RFOP002), managing authority: Subdirección General de Gestión del FEDER, de la Dirección General de Fondos Europeos del Ministerio de Hacienda.. The source names no beneficiary for this operation. Location: Barcelona Province (NUTS ES511); Spain. Budget: total eligible expenditure EUR 166,583; EU co-financing EUR 83,291.5 (co-financing rate 50%), as stated by the source. Runs 2019-01-01 to 2020-12-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS); selected because its summary names quantum technology. Summary from Kohesio (English machine translation by the source): Strontium is an alkali-earth atom with two valence electrons in its outer shell, resulting in ideal optical properties for developing various research lines in quantum optics and atomic physics. These include: (i) the study of quantum light-trapped atoms interfaces where collective interference effects play a central role, with applications in quantum memories, strongly correlated photon states and many-body metrology; (ii) the realization of quantum simulators with artificial gauge fields and long-range interactions exploiting Rydberg states. In this project, we request a laser system for cooling and manipulating ultracold strontium atoms. This system will: (i) provide light resonant with the 461 nm and 689 nm optical transitions of strontium and of adequate spectral properties in order to cool the gas and realize quantum atom-light interfaces; (ii) trap the atoms at a magic wavelength (515 nm), allowing for homogeneous excitation of the system on the 689 nm transition. The laser system should include lasers at 461 nm, 515 nm and 689 nm, a wavemeter and an ultrastable optical cavity to stabilize them. It will enable the development of a novel experimental platform based on two-electron atoms, making new scientific collaborations and theoretical and experimental research lines possible in the Barcelona region.
