从核磁共振到激光

NUCLEAR MAGNETIC RESONANCE AND THE ADVENTOF LASERS

从量子电子学和激光物理的重要物理概念的历史发展中探讨了它与核磁共振的渊源关系，并揭示了核磁共振对量子电子学和激光发展所作的重要贡献，特别就原子系统与辐射场的共振相互作用的动力学过程，相互作用的相位相干和集体作用的重要性，原子能级布居数调控方法与实现布居数反转办法，谐振腔和回路在与辐射相互作用中的功能，以及相干瞬态现象的产生与解释等方面，说明了核磁共振所起的重要作用。本文为纪念凝聚态物质核磁共振诞生５０周年而作。

n this paper, a historical review of the Quantum Eletuonirs and Laser Physica isgiven in the context of the physical coneepts originated from the nuclear magnetic res-onance which has made great contributions to their development.The following aspects which play an important role in their development are par-ticularly considered. the dynamica of interaction of atomic systems with radiationin the real sense of thearesonance″, the importance of the cooperative interaction of at-onis in which the phase coherence plays a significant role, the different methods andmechanisms for manipulation of population distribution of atoms including the popu-lation invereion, the functions of the resonant circuits and the cavities in the interactionand the emergence and the explanation of the coherent transient phenomena. This pa-per is devoted to the 50th annivereary of the advent of the nuclear magnetic resonancein condensed matter.
