摘要/Abstract

摘要：应用含保守系统和非保守系统的薛定谔方程分析了激光冷却机制，用该理论证明了原子在激光场中被冷却.并预言了原子冷却温度与原子振动频率成正比，该结论与最近在Nature发表的实验结果完全一致.

关键词： 量子理论, 原子冷却, 冷却温度

Abstract: The laser cooling mechanisms with extended Schrodinger quantum wave equation is studied,which can describe a particle in conversative and non-conversative force field.With this theory,it is proved that the atom in laser field can be cooled,and it is predicted that the atom cooling temperature T is directly proprtional to the atom vibration frequency,which are in accordance with experiment results.

Key words: quantum theory, laser cooling, cool temperature
