摘要/Abstract

摘要：

该文开展利用Ramsey干涉现象设计被动型氢原子钟的可行性研究. 该方案的核心是用脉冲微波激励氢原子发生共振跃迁. 通过理论计算确定了关键参数，研制了脉冲微波发生电路. 利用现有的被动型氢原子钟的物理部分，成功观察到氢原子共振跃迁的Ramsey干涉，将原子跃迁谱线宽度从原来的3 Hz压缩至1.2 Hz. 这为进一步提高被动型氢原子钟的稳定度指标提供了一种新思路.

Abstract:

The feasibility of inducing Ramsey interference by pulsed microwave in hydrogen maser was studied. The key parameters were theoretically determined, and a pulsed microwave signal generator was designed. The Ramsey interference of hydrogen atoms was induced successfully on the physical package of a traditional passive hydrogen maser. Line width of the hydrogen atomic transition was reduced from 3.0 Hz to 1.2 Hz. It is expected that the frequency stability of passive hydrogen maser could be improved by using the design.

Key words: hydrogen maser, Ramsey interference, pulsed microwave, line width
