The PICAS Photonically Integrated Cold Atom Source from Inflection offers a compact and alignment-free solution for generating a high-flux beam of cold atoms. The source uses user-supplied, fiber-coupled light to efficiently cool and transport rubidium or cesium atoms. When the PICAS is equipped with a ColdQuanta source cell it can be easily integrated into the user's vacuum system via a standard CF interface. Since the optomechanical unit can be removed if necessary, this enables an uncomplicated bake-out of the system.
Innovative beam expansion technology
The PICAS uses a patented, ultra-compact beam expansion system that generates a rectangular beam of circularly polarized light. The intensity of the beam remains evenly distributed thanks to the use of cylindrical lenses and a distribution optic. The setup includes two of these beam expander units as well as two retro-reflection mirrors and a push optic. These components are optimally coordinated with one another and are precisely aligned and bonded before the cold atom tests.
Robust and vibration-resistant cold atom source
All optical systems of the PICAS are firmly pre-adjusted and bonded in a vibration-resistant manner. This design ensures that the system remains robust and resistant to shocks. Since no manual adjustment is required, the PICAS can be operated in any orientation independent of gravity. This makes the cold atom source particularly versatile.
Flexible structure and compatibility
The PICAS offers flexibility in alignment, making it ideal for a wide range of applications in quantum research. It is also compatible with rubidium or cesium sources and supports a wide range of settings and adjustments. Precise adjustment is possible thanks to the three fiber-coupled inputs for optical FC/APC connectors and the possibility of XY adjustment of the optics and magnets.
Easy integration and operation
With the compact design of only 67 mm x 67 mm x 93 mm and the standardized CF interfaces, the PICAS can be easily integrated into existing vacuum systems. The simple assembly and robust design make it an ideal solution for users looking for a reliable and powerful cold atom source. The PICAS Photonically Integrated Cold Atom Source stands for precision and user-friendliness in modern quantum research.
