最近的理论发展强调了干涉仪中的“光学弹簧”作为超越标准量子极限的手段对引力波探测的潜在重要性。我们在失谐法布里-珀罗谐振腔中实验观察到光学弹簧效应，其中一个反射镜安装在弯曲件上，使得它对辐射压力有显著的响应。光学弹簧的主要效果是观察到的可移动反射镜的机械共振频率的偏移，这与简单模型吻合得很好。
Recent theoretical developments have highlighted the potential importance of "optical springs" in interferometers for gravitational wave detection as a means for beating the standard quantum limit. We have observed an optical spring effect experimentally in a detuned Fabry-Perot resonator in which one mirror is mounted on a flexure so that it has a significant response to radiation pressure. The main effect of the optical spring, an observed shift in the mechanical resonance frequency of the moveable mirror, agrees well with a simple model.
