Fibered laser system for rubidium laser cooling based on telecom technology at 1560 nm and frequency doubling

In conclusion, we have developed a new laser system to laser cool rubidium atoms based on frequency doubling of a 1560 nm fiber bench. The use of telecom components gives us a reliable and compact system robust compare to environmental perturbations. Our laser system should find applications for onboard cold atoms experiments like inertial captors or atomic clocks. For example, our laser could be used in matter wave interferometers in space like the project ICE supported by CNES. We should also point out that our laser system can also address potassium atoms which have a laser cooling wavelength of 767 nm.
