【摘要】 光学微腔中原子之自发辐射与自由空间中原子的自发辐射有着重要的不同。微腔能够控制腔内原子的自发辐射,使自发辐射得到抑制或增强,并有可能使自发辐射成为一个可逆过程。由此发展起来的腔量子电动力学能够阐述腔场与原子的相互作用。本文简要介绍了这一研究领域的背景和进展,同时介绍了微腔的重要应用-无阈值激光器。更多还原

【Abstract】 The behavior of spontaneous emission of atoms in microcavities is significantly different from that in free space. The spontaneous emission is controlled by microcavity, it can be enhanced or restrained, even can become a reversible process. Interaction of the cavity field with an atom is expound by the cavity quantum electrodynamics. We briefly introduce the basic ideas of this subject and its recent progress, also introduce an important application of microcavity-the threshold-less laser.更多还原
