The research of motorial characteristic of sodium atoms in standing wave field
中性钠原子在激光驻波场中的运动特性研究

Direct write atom lithography is a new technique in which resonant light is used to pattern an atomic beam and the nanostructures are formed when the atoms deposit on the substrate. The motion of sodium atoms in standing wave filed is discussed. Based on the semi-classical model,this paper analyses the motion equation of sodium atom in the laser standing wave field,and then gets the trajectory of the atoms in the standing wave field by analytical simulation for different longitudinal and transverse velociti...
