| Abstract: | A control system of the VCSEL based on CPT atomic clock is designed in this paper.The whole system contains a precise and high stable DC power with the range of 20mA and lower noise.The composition and working principle of the VCSEL control system are introduced.Additionally,the VCSEL control system is tested and analyzed.The experimental results show that the control system can achieve single-mode state,narrow line-width and a stable low-power light source. It has a reference and useful value for the application of VCSEL light source based on CPT atomic clock. |
