摘　　要：高精度重力测量是进行惯性导航、大地测量、空间科学、海洋探测、基础物理研究的重要观测手段,高精度的重力仪一直是科学研究追求的目标。原子干涉重力仪能够提供uGal量级的绝对重力加速度值,是获取高精度重力信息的重要仪器之一,其集成光源系统的设计及实现对其实用化和商业化具有重要意义。首先介绍原子干涉重力仪激光系统的输出需求,然后对国内外典型集成光源系统的相关研究发展进行综述,分别介绍了基于自由空间和光纤传输的两种光源系统的实现方案和发展现状,重点阐述了其稳频、跳频、稳功率等关键技术。最后,对原子干涉重力仪集成光源系统的进行了总结与展望。High-precision gravity measurement is an important observation method for inertial navigation, geodesy, space science, ocean exploration, and basic physics research. High-precision gravimeter has always been the goal pursued by scientific research. Atom interferometry gravimeter can provide absolute gravity acceleration of uGal magnitude. It is one of the most significant instruments to obtain high precision gravity information. The design and implementation of its compact laser system is of great significance for its practicality and commercialization. Firstly, the output requirements of atom interferometry gravimeter laser system are introduced, and then the related research and development of compact laser system at home and abroad are reviewed, and the implementation schemes and development status of two kinds of light source systems based on free space and optical fiber transmission are introduced respectively, with emphasis on its key technologies such as frequency stabilization, frequency hopping, power stabilization and so on. Finally, the compact laser system of atom interferometry gravimeter is summarized and prospected.
