Magneto-optical trap for cold atom device, has optical separator arranged in order to separate primary optical beam into set of secondary beams having identical intensity, and optical units arranging secondary beams around vacuum chamber

摘要

The trap (1) has an optical source (2) generating primary optical beam, and an optical separator (10) i.e. phase network, arranged in order to separate the primary optical beam into a set of secondary beams (30) having identical intensity. Optical units i.e. optical fibers (6), arrange the secondary beams around a vacuum chamber (4). The optical separator comprises a set of identical patterns, where the length of each pattern is equal to that of the optical separator that is formed on a transparent flat substrate.
