摘要

摘要: 窄线宽激光凭借其极低的相位噪声，在量子技术、时频传输、高精度传感等前沿领域发挥着至关重要的作用。回音壁模式光学微腔，得益于其高品质因子、小模式体积和宽光学透明窗口的特性，能够极大地增强光与物质的相互作用，不仅在较宽的谱段范围内可以获得良好的激光线宽压窄效果，而且具有良好的可调谐特性，因此成为了窄线宽激光研究领域的热点。回顾了基于回音壁微腔的窄线宽激光研究进展，首先介绍了回音壁微腔及其热噪声理论基础和激光线宽评价原理，随后讨论了当前基于回音壁微腔产生窄线宽激光的主要方法，包括基于受激布里渊散射与受激拉曼散射效应的泵浦式窄线宽激光，以及基于自注入锁定与PDH锁定技术的锁定式窄线宽激光，梳理了它们的研究现状、关键技术特点以及性能指标。介绍了中国计量科学研究院在基于高品质因子晶体回音壁微腔窄线宽激光方面的研究进展，并对回音壁微腔窄线宽激光的发展进行了总结与展望。

Abstract: Narrow linewidth lasers play a vital role in cutting-edge fields such as quantum technology, time-frequency transmission, and high-precision sensing due to their extremely low phase noise. Whispering gallery mode optical microcavities, owing to their high quality factor, tiny mode volume, and wide optical transparent window, can significantly enhance the interaction between light and matter. These microcavities not only achieve good laser linewidth narrowing effects across a wide spectral range but also offer excellent tunability, making them a hot topic in narrow linewidth laser research. This paper reviews the research progress of narrow linewidth lasers based on whispering gallery mode microcavities. It first introduces whispering gallery mode microcavities, their thermal noise theoretical foundation, and the principles of laser linewidth evaluation. Then, it discusses the main methods for generating narrow linewidth lasers using whispering gallery mode microcavities, including pumped narrow linewidth lasers based on stimulated Brillouin scattering and stimulated Raman scattering effects, as well as locked narrow linewidth lasers using self-injection locking and Pound-Drever-Hall (PDH) locking technologies. The research status, key technical characteristics, and performance metrics of these methods are summarized. Additionally, the research progress of the National Institute of Metrology in developing narrow linewidth lasers based on high quality factor crystal whispering gallery mode microcavities is introduced. Finally, the paper provides a summary and outlook on the development of narrow linewidth lasers based on whispering gallery mode microcavities.
