11W narrow linewidth laser source at 780nm for laser cooling and manipulation of Rubidium
ANU's Quantum Sensors and Atom laser Group have demonstrated an 11W narrow linewidth laser source. Using a 30W 1560nm fiber laser in a single-pass frequency doubling scheme, Sané and coworkers achieved a 6kHz linewidth 780nm laser with 36% efficiency.
This high power 780nm laser source is simple and robust, and has demonstrated over 2200hrs of operation with no reduction in power. This system will be used for laser cooling and manipulation of rubidium and has applications in wide variety of atomic physics experiments, including precision atom interferometry.
