现代地面引力波(GW)探测器需要具有多个耦合光腔的复杂干涉仪配置。由于获得臂腔的谐振是锁获取过程中最具挑战性的过程，因此被称为臂长度稳定(ALS)的方案被应用于臂腔的锁定获取。我们设计了一种新型的ALS，它与像下一代GW探测器一样具有长臂的干涉仪兼容。新的ALS的特点是控制结构比以前的简单，并且不需要沿着探测器的千米长的臂为ALS铺设光纤。在对其噪声性能进行仿真的同时，利用KAGRA的单臂腔体对新的ALS进行了实验测试。本文介绍了测试的第一个结果，其中我们证明了使用新的ALS实现了对手臂腔的锁定获取。我们还证明，剩余噪声的均方根以频率为单位测量为8.2赫兹，小于臂腔的线宽，从而足以以可重复和可靠的方式锁定KAGRA的全干涉仪。
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the arm cavities is the most challenging among the lock acquisition processes, the scheme called arm length stabilization (ALS) had been employed for lock acquisition of the arm cavities. We designed a new type of the ALS, which is compatible with the interferometers having long arms like the next generation GW detectors. The features of the new ALS are that the control configuration is simpler than those of previous ones and that it is not necessary to lay optical fibers for the ALS along the kilometer-long arms of the detector. Along with simulations of its noise performance, an experimental test of the new ALS was performed utilizing a single arm cavity of KAGRA. This paper presents the first results of the test where we demonstrated that lock acquisition of the arm cavity was achieved using the new ALS. We also demonstrated that the root mean square of residual noise was measured to be 8.2 Hz in units of frequency, which is smaller than the linewidth of the arm cavity and thus low enough to lock the full interferometer of KAGRA in a repeatable and reliable manner.
