Abstract

Accurate and traceable length metrology is employed by laser frequency stabilization. This paper describes a laser frequency stabilization technique as a secondary standard with a fractional frequency stability of 5.2x10(-10) with 2 mW of power, suitable for practical applications. The feedback stabilization is driven by an intrinsic mixed mode signal, caused by nonlinear optical phenomena with adjacent modes. The mixed mode signals are described theoretically and experimentally verified.

摘要

激光频率稳定采用精确且可溯源的长度计量。本文描述了一种激光频率稳定技术，作为一种二级标准，在2毫瓦功率下具有5.2×10⁻¹⁰的分数频率稳定性，适用于实际应用。反馈稳定由相邻模式的非线性光学现象引起的固有混合模式信号驱动。对混合模式信号进行了理论描述和实验验证。
