ITT_127467 - High Power Laser System with Output at 461nm

The National Physical Laboratory (NPL) requires a 461 nm laser system to prepare mK-level Strontium (Sr) in the Sr optical lattice clock. To efficiently cool down sufficient atoms, the first cooling stage requires >100 mW blue light for a blue magneto-optical trap (MOT) and >200 mW for a Zeeman slower. In addition, the current experimental apparatus has a fibre coupled input. Thus, the requested high-power blue laser system is expected to deliver well in excess of this optical power out of an optical fibre. The Sr...
