An extended cavity diode laser constructed with additive manufacturing: Contribution for a brazilian compact atomic frequency standard with cold atoms

The Time and Frequency Metrology field dedicated towards more compact standards has research groups dedicated to cold atoms systems, in order to improve embedded applications. Our group has been developing a compact system using 133Cs cold atoms and already showed some versions of proof-of-principle. We developed a first prototype of an extended cavity diode laser using additive manufacturing of ABS (acrylonitrile butadiene styrene) and obtained a very light and thermally isolated version with an intracavity interference filter. We will show preliminary results of this first version and discuss some aspects of the system for the new compact frequency standard.
