我们报告了具有能量回收功能的悬浮质量失谐谐振边带提取 (RSE) 干涉仪的光学响应。失谐 RSE 配置的目的是操纵和优化干涉仪对作为频率函数的微分位移（由引力波引起）的光学响应，而与干涉仪的其他参数无关。我们的干涉仪设计产生具有两个峰值的光学增益：4 kHz 左右的 RSE 光学谐振和 41 Hz 左右的辐射压力诱导光学弹簧。我们开发了一种可靠的程序来获取锁定并建立所需的光学配置。在这种配置中，我们测量了对差分位移的光学响应，并发现与共振和所有其他相关频率的预测非常一致。这些结果为高级 LIGO 计划的更复杂的光学配置的理论和实际实施奠定了信心。
We report on the optical response of a suspended-mass detuned resonant sideband extraction (RSE) interferometer with power recycling. The purpose of the detuned RSE configuration is to manipulate and optimize the optical response of the interferometer to differential displacements (induced by gravitational waves) as a function of frequency, independently of other parameters of the interferometer. The design of our interferometer results in an optical gain with two peaks: an RSE optical resonance at around 4 kHz and a radiation pressure induced optical spring at around 41 Hz. We have developed a reliable procedure for acquiring lock and establishing the desired optical configuration. In this configuration, we have measured the optical response to differential displacement and found good agreement with predictions at both resonances and all other relevant frequencies. These results build confidence in both the theory and practical implementation of the more complex optical configuration being planned for Advanced LIGO.
