CPT原子钟系统光源温度控制设计与实现

摘要

The factors affecting the wavelength of Laser Diode ( LD) were presented. A circuit for wavelength precisely stabilization was designed and realized for coherent population trapping atomic clock. Experiment tests showed that the wavelength could be stabilized within 0. 02 degree C hy the circuitry. Corresponding wavelength control accuracy was 0. 001 2nm.%介绍了半导体激光器波长影响机理,针对相干布局数囚禁(CPT)原子钟系统光源,设计并制作了通过半导体激光器的温度稳定的电路.实验结果表明,采用此电路的激光器,其温度稳定度约为0.02℃,相应波长稳定度可达0.0012 nm.
