摘要： Embodiments of the invention are directed to an atomic-based frequency reference that includes an architecture that eliminates the need for local oscillator components and instead is implemented with a “photonic local oscillator,” that provides for a relatively low power consumption, compact, atomic clock/frequency reference. Such a system is based on a laser cavity which contains an alkali-vapor-cell within the laser cavity. The laser cavity is designed to oscillate in two or more optical wavelengths, with the frequency difference of these lasing wavelengths equal to the atomic hyperfine resonance frequency. Embodiments of the system can include relatively few elements, namely: a) an optical gain element with an emission band centered at the atomic absorption band; b) collimating optics; c) an atomic vapor cell; and d) a cavity end mirror. Optionally, specific polarization optics may be used depending on the specifics of the optical pumping.
摘要翻译：本发明的实施例涉及一种基于原子的频率参考，其包括消除对本地振荡器组件的需要的体系结构，而是用“光子本地振荡器”来实现，其提供相对低的功率消耗，紧凑的原子时钟 /频率参考。这种系统基于在激光腔内包含碱蒸汽电池的激光腔。激光腔被设计成以两个或更多个光波长振荡，这些激光波长的频率差等于原子超精细共振频率。该系统的实施例可以包括相对较少的元件，即：a）具有以原子吸收带为中心的发射频带的光学增益元件; b）准直光学; c）原子蒸汽池; 和d）腔端镜。可选地，可以使用特定偏振光学器件，这取决于光学泵浦的细节。
