摘　　要：光钟是基于原子钟的光学频率为基准下制造的一种时间计数器，它是在航行、地球定位系统、军事等领域有着广泛应用价值。光钟由三个组成部分来实现：一是激光冷却、二是稳频激光器、三是能将光学频率分配成可以被计数的微波频率的频率分配器。由于它有方便、精确度高等特点，在精密计时方面广泛应用。本文介绍了光钟的发展历史、原理以及光钟装置。The optical clock is a time counter based on the optical frequency of the atomic clock. It is widely used in navigation, the global positioning system, and the military and other fields. The realization of the clock is composed of four parts which include laser cooling, frequency stable laser, ion trap and frequency divider that can allocate the optical frequency to the microwave frequency that can be counted. Because of its convenience and accuracy, it is widely used in precision timing. In this paper, the development history, principle and physical devices of optical clock are introduced.
