标题： Shot-Noise-Limited Laser Frequency Stabilization Using a High-Resolution Wavelength Meter

摘要： 我们提出了一种紧凑的激光频率稳定方法，通过将556 nm激光锁定到高精度波长计来实现。 与依赖光学腔体或原子参考的传统方案不同，我们通过以波长计为参考的闭环反馈系统来稳定激光频率。 这种配置有效抑制了长期频率漂移，实现了达到波长计散粒噪声极限分辨率的频率稳定性。 该系统无需复杂的光学元件即可实现亚百千赫兹的稳定性，适用于紧凑或现场部署的应用。 我们的结果表明，通过适当的反馈设计，基于波长计的锁定可以为需要长期频率稳定性的精密光学实验提供一种实用且可扩展的解决方案。 显示英文摘要

摘要： We present a compact laser frequency stabilization method by locking a 556 nm laser to a high-precision wavelength meter. Unlike traditional schemes that rely on optical cavities or atomic references, we stabilize the laser frequency via a closed-loop feedback system referenced to a wavelength meter. This configuration effectively suppresses long-term frequency drifts, achieving frequency stability to the wavelength meter's shot-noise-limited resolution. The system enables sub-hundred-kilohertz stability without complex optical components, making it suitable for compact or field-deployable applications. Our results demonstrate that, with proper feedback design, wavelength meter-based locking can offer a practical and scalable solution for precision optical experiments requiring long-term frequency stability.
