| Abstract: | The use of the dipole force on atoms is a new technology that is used to build nanostructures.In this way,a high quality standard nano-grating can be obtained.Based on the semi-classical model,the motion equation is investigated and the trajectories of atoms in double half Gaussian standing wave field are simulated.Compared with the Gaussian standing wave field,the double half Gaussian standing wave can well focus the Cr atoms.In order to obtain this kind of beam,a prism is designed and the experimental result shows that the beam is well generated. |
