PICAS: Photonically Integrated Cold Atom Source
ColdQuanta’s PICAS, Photonically Integrated Cold Atom Source, is a compact, alignment-free package that produces a high-flux beam of laser-cooled atoms, using user-supplied, fiber-coupled light. When combined with a ColdQuanta source cell, the PICAS is easily integrated into the end user’s vacuum system through a standard CF interface, and the opto-mechanics unit can be removed during bake-out.
The PICAS employs our patent-pending, ultra-compact beam expansion system. This unit produces a rectangular beam of circularly polarized light with an approximately uniform intensity profile via a combination of cylindrical lenses and a distribution optic.
