Application of Laser Cooling in Atomic Beam Imaging by a Hexapole Magnetic Lens

Li Chuanwen Cai Weiquan Wang Yuzhu (Laboratory for Quantum Optics, Shanghai Institute of Optics and Fine Mechanics, The Chinese Academy of Sciences, Shanghai 201800)  
The principle of the atom lens using a hexapole magnetic field and its aberration has been discussed. Comparison of the focusing results of a hot atomic beam with a monochromatic cold atomic beam shows that the main factor affecting the imaging quality of the magnetic lens is chromatic aberration. The use of laser cooling atomic beam technique can greatly reduce this aberration and makes the magnetic lens a useful tool in the field of atomic optics.
