Magneto-optical trapping of strontium for use as a mobile frequency reference

摘要: Atomic Caesium clocks have made an astonishing development in the past few decades, with them gaining order of magnitude precision every decade. A new generation atomic optical is now emerging, which moving to forefront timekeeping. By going from microwave frequencies these are reaching fractional uncertainty levels 10\(^-\)\(^1\)\(^8\), opening a whole range exciting applications. This thesis presents design and implementation experiment for laser cooling strontium atoms, focusing on mobility setup, applications as mobile clock. The experimental apparatus applies techniques strontium, such use two dimensional magneto-optical trap pre allowing compact transportable system. system atoms was realized. includes frequency doubling main transition. constructed monolithic cavity has generated 300 mW blue light proven be stable setup suitable 3D-MOT able capture 4 * 10\(^5\) long lifetime 5.5 s, further improvements significant increase atom number currently being implemented.
