laser引力波探测器中稳定的双共振光学弹簧
Stable double-resonance optical spring in laser gravitational-wave detectors
摘要：
分析了双泵浦法布里-珀罗腔的光弹簧特性。当光学弹簧频率与腔体的失谐频率一致时，出现双共振光学弹簧。我们制定了一个简单的标准，光学弹簧的稳定性，并将其应用到双共振制度。双共振组态对于未来的引力波探测器是非常有希望的，因为它们允许我们超越标准量子极限。我们表明，稳定的双共振可以证明在中等规模的原型干涉仪，如格拉斯哥10米原型，金高光功率测试设施或AEI 10米原型干涉仪在未来的引力波探测器实施之前。
英文摘要：
We analyze the optical spring characteristics of a double pumped Fabry-Perot cavity. A double-resonance optical spring occurs when the optical spring frequency and the detuning frequency of the cavity coincide. We formulate a simple criterion for the stability of an optical spring and apply it to the double resonance regime. Double resonance configurations are very promising for future gravitational wave detectors as they allow us to surpass the Standard Quantum Limit. We show that stable double resonance can be demonstrated in middle scale prototype interferometers such as the Glasgow 10m-Prototype, Gingin High Optical Power Test Facility or the AEI 10m Prototype Interferometer before being implemented in future gravitational wave detectors.
