The invention provides a folding light path
laser cooling atom device which is mainly composed of a vacuum tetrakaidecahedron, cooling
light source assemblies, reflecting mirror assemblies, transfer mirror assemblies and anti-helmholtz
magnetic field coils. The folding light path
laser cooling atom device integrates a
laser beam expansion collimation
system, a folding light path, a polarization transformation
system, the anti-helmholtz
magnetic field coils and
optical power real-time monitoring, six paths of laser required by a traditional
laser cooling magneto optical trap is reduced to two paths of laser, the size and weight of an optical-
mechanical system are reduced to the maximum degree, a space topology structure is simplified, and the optical-
mechanical system is
extremely good in
mechanical property and thermal environment adaptability and can be applied to the severe environment of the space level. According to the folding light path
laser cooling atom device, samples have passed ring die tests, such as a space level
mechanical vibration test, a
mechanical impact test, a
thermal cycle test and a thermal vacuum test, long-term stable working can be kept, and the device can serve as a core optical-mechanical device of the laser cold atom
application engineering.
