摘要
原子干涉仪在精密测量和惯性导航领域都有着重要前景,而高精度的原子干涉仪对低相位噪声、高输出功率的拉曼激光有迫切需求.设计了基于光学锁相环路的双波长激光同步注入放大拉曼激光制备方案,实现了大功率拉曼激光的制备,拉曼光注入放大前后的相位噪声均低于-80 dBc@0.01～1 MHz,输出总功率达到了400 mW,可满足原子干涉精密测量的需求.
Atom interferometry has important prospect in the precise measurement and inertial navigation fields. The high-precision atom interferometer has an urgent need for Raman lasers with low phase noise and high output power. A dual-wavelength synchronous injection-amplification Raman laser preparation scheme based on optical phase-locked loop is designed, and the preparation of high-power Raman laser is achieved.The phase noises of Raman lasers before and after amplification are both below -80 dBc@0.01～1 MHz, and the total output power reaches 400 mW, which can meet the needs of atom interferometer based precision measurement.
