单原子激光器的建立及其物理含义过去几年中，物理学家已将原子从抽象概念变成为有形物体。能将原子在陷阱中隔离，能用特殊的显微镜看到原子，能用光学“镊”搬移原子。甚至已将单个原子用作毫微级开关中的运动零件。今天，麻省理工学院的一个物理学家小组已把原子级技术... The establishment of the single-atom laser and its physical implications In the past few years, physicists have transformed atoms from abstract concepts into tangible objects. The atom can be trapped in the trap, can use a special microscope to see the atom, the optical “tweezers” to move the atom. Even a single atom has been used as a moving part in a nano-scale switch. Today, a group of physicists at the Massachusetts Institute of Technology has put atomic technology ...
