利用近共振激光驻波场操纵中性原子实现纳米级条纹沉积是一种新型的研制纳米结构长度标准传递方法，但仅通过一维和二维形式的仿真不能给出激光驻波场作用下中性原子沉积纳米光栅的全部信息。利用半经典模型，从铬原子在高斯激光驻波场中的运动方程出发，通过四阶Rungo-Kutta法模拟了铬原子在高斯激光驻波场中的三维运动轨迹以及三维沉积条纹结构，并分析了原子束发散、色差和球差等因素对三维运动轨迹及沉积条纹结构的影响。结果表明，利用三维仿真形式模拟高斯激光驻波场中铬原子的运动得到的结果与一维和二维形式下相比可以直观地表现出其较为详细的本质。

Nanostructures stripe deposition technique is a new method to develop nanostructures length standard transmission with the near resonance laser wave field manipultaion in neutral atoms. But all the information of nano-gratings deposited by laser standing wave field can not be given only through the one-dimensional or two-dimensional. The semi-classical model is used to simulate the three-dimensional trajectory and deposition distribution of the chromium atoms in the Gaussian laser standing wave field using the Runge-Kutta method from their motion equation in laser standing wave field. Then the three-dimensional deposition stripes are given, moreover, the effects of atomic beam divergence, chromatic aberration and spherical aberration on deposition structure are also analyzed. The study shows that results of three-dimensional simulation in Gaussian laser standing wave field of Cr can visually demonstrate the more detailed innate characters.
