原子的激光冷却近年来，物理学家终于用激光束形成的“光学粘团”方法捕获和固定小原子云。原子能够在粘团中活动的速度很小（每秒几厘米），对应的温度约为绝对温度的百万分之一。冷原子的获得不仅是技术上的一大功绩，而且深化了对原子和光相互作用的认识以及尚未预见的... Laser cooling of atoms In recent years, physicists have finally captured and immobilized small atomic clouds using the “optical sticking” method of laser beam formation. Atoms can move very slowly in the mass (a few centimeters per second), and the corresponding temperature is about one millionth of an absolute temperature. The acquisition of cold atoms is not only a mega-feat of technology, but also deepens the understanding of the interaction of atoms and light as well as unforeseen ...
