标题： Sub-SQL Sensitivity via Optical Rigidity in Advanced LIGO Interferometer with Optical Losses

摘要： “光学弹簧”模式的激光干涉引力波探测器信号再循环配置被分析，考虑了干涉仪臂腔中的光学损耗。 该模式允许在自由测试质量以及常规谐波振荡器的情况下获得优于标准量子极限的灵敏度。 光学损耗限制了灵敏度的提升和可实现的信噪比。 然而，对于先进LIGO引力波探测器计划的参数值，这种限制是微不足道的。 显示英文摘要

摘要： The ``optical springs'' regime of the signal-recycled configuration of laser interferometric gravitational-wave detectors is analyzed taking in account optical losses in the interferometer arm cavities. This regime allows to obtain sensitivity better than the Standard Quantum Limits both for a free test mass and for a conventional harmonic oscillator. The optical losses restrict the gain in sensitivity and achievable signal-to-noise ratio. Nevertheless, for parameters values planned for the Advanced LIGO gravitational-wave detector, this restriction is insignificant.
