| 汞离子微波频标利用汞灯进行抽运，可实现小型化，同时具备体积小、指标高的优势，未来可在卫星导航、深空探测和守时中得到广泛应用。为了提高抽运效率及降低噪底，需要进行汞灯光学设计，使抽运光通过四极阱中心与囚禁离子充分作用的同时减少与真空腔及四极杆的反射。首先提出遮挡光源法和非等比例放大法两种光学设计方法。然后介绍了两种设计方法的具体设计过程和设计结果，并比较了两种光学设计方法汞灯的能量利用率。最后利用非等比例放大法进行光路优化设计，并完成了物理系统信号探测实验。实验结果表明：采用该光学设计方案，汞离子光微波双共振跃迁信号幅度提高了20%以上。 |
| 英文摘要: |
| The mercury ion trapped microwave frequency standard is pumped by the mercury lamp, and can achieve miniaturization. It has potential wide applications for the future satellite navigation, deep space explorations and time keeping for its advantages of small volume and high performance indicators. In order to improve pumping efficiency and reduce noise background, it is necessary to carry out optical design of mercury lamps, so that the pumping light can fully interact with trapped ions through the center of the quadrupole trap well while reducing reflection from the vacuum cavity and quadrupole rods. Firstly, two optical design methods, occlusion light source method and non proportional amplification method, are proposed. Then, the specific design process and results of the two design methods were introduced, and the energy utilization efficiency of the two optical design methods for mercury lamps was compared. Finally, the non proportional amplification method was used for optical path optimization design, and physical system signal detection experiments were completed. The experimental results show that using this optical design scheme, the amplitude of mercury ion light microwave dual resonance transition signal has been increased by more than 20%. |
