摘要
设计了一套紧凑可靠的87Rb 原子干涉重力仪激光系统。该激光系统仅采用两台包含锥形放大器的半导体激光器作为光源，通过简单、巧妙的设置，实现原子干涉仪中所需的9 种频率的激光。系统中包含2 个电学伺服系统，用于实现激光的频率稳定和一对拉曼光的获得，其他频率激光均在2 束拉曼光的基础上通过声光调制器移频实现，满足对各束光的频率和功率的控制要求。整个系统设计紧凑，性能可靠。
Abstract
A laser system design is presented for an absolute gravimeter based on 87Rb atom interferometer. By skillful design, lasers with 9 kinds of different frequency are based on two diode lasers including tapered amplifier. Two electrical feedback systems are used for laser frequency stabilization and generating the Raman lasers, respectively. All other lasers are based on two Raman lasers and realized with frequency shifting by acoustic optical modulators. This laser system not only has the compact and simple construction, but meets all the requirements for laser power and frequency controlling. It has the characteristic of reliability and integrity.
