激光冷却铬原子的3维仿真分析
3-D analysis of laser-cooling Cr atoms
摘要
Abstract
In order to study the 3-D features of Cr atoms in laser cooling field, the interaction process of Cr atom and laser cooling field was analyzed. Based on the semi-classical theory of Doppler and polarization gradient force, the fourth-order Runge-Kutta algorithm was adopted to simulate 3-D trajectory of Cr atoms, at the same time, three-dimension distribution of them was also obtained. After passing through laser cooling field, the divergence angle of Cr atomic beam becomes smaller, and the corresponding velocity also decreases. The results show that the three-dimension features of Cr atoms agree with the two-dimension cases, and can provide more comprehensive, richer cooling information.关键词
