Abstract: 
In recent years, many systems based on quantum effects have been applied to precision measurement. A laser pumped helium 4 absolute scalar atomic magnetometer which is carried by the Swarm satellite is used to measure the earth magnetic field intensity. China launched the first cold atomic clock in 2016, in which frequency stabilized laser systems were very important. A compact cold atom gravimeter was developed for field application. Most of these systems, which require frequency stabilized laser systems, are placed on moving platforms. The vibration of these platforms is an important noise source to the laser frequency because the long-term changes of adjustable parts may occur under the vibration condition.

用于激光锁频的低泵浦场饱和吸收光谱

目的:利用激光透过原子气室时的端面反射产生泵浦光,实现低泵浦场的饱和吸收光谱,提高饱和吸收光谱锁频方法对运动平台的适应性.
创新点:1. 在饱和吸收光谱中实现无需额外反射镜调节的泵浦光与探测光的重合方法; 2. 在饱和吸收光谱中实现强探测-弱泵浦的实验方式.
方法:1. 利用原子气室端面反射光作为泵浦光,实现低泵浦场的饱和吸收光谱装置(图1和2); 2. 研究实现低泵浦场的饱和吸收光谱所需的角度控制精度(图4); 3. 研究采用此方法的激光频率锁定效果(图5和6).
结论:1. 低泵浦场的饱和吸收光谱方法可以满足激光频率锁定的要求; 2. 低泵浦场的饱和吸收光谱装置相比传统装置,没有多余的可调节的反射镜,装置更加简洁,锁频效果受环境影响更小,对运动平台的适应性更强.
