摘要
现代地基引力波（GW）探测器需要具有多个耦合光学腔的复杂干涉仪配置。由于在锁定的获取过程中臂腔共振的实现最具挑战性，被称为臂长稳定（ALS）的方案已被用于臂腔的锁定获取。我们设计了一种新型 ALS，其与具有长臂的干涉仪（如新一代 GW 探测器）兼容。新 ALS 的特点是控制配置比以往更简单，且无需沿探测器的公里级长臂为 ALS 铺设光纤。在对噪声性能进行仿真的同时，利用 KAGRA 的单臂腔对新 ALS 进行了实验测试。本文给出该测试的初步结果：我们展示了利用新 ALS 实现了臂腔的锁定获取，并测得残差噪声以频率为单位为 ，小于臂腔线宽，因此足够低以可重复且可靠地锁定 KAGRA 的全干涉仪。
