在我们看来,未来设计引力波干涉探测器最重要的两个问题是热噪声和光学噪声。在本文中,我们讨论了一些降低这些噪声的方法。关于热噪声,我们展示了一种可能的低温解决方案。关于光学噪声(即散粒噪声和辐射压力噪声的组合效应),我们证明了应用最近提出的基于“量子反馈”的减少策略是可能的(Courty等人,2003,Phys。莱特牧师。90 083601;Courty等人2003年预印GR-QC/0301068)至全法布里-珀罗腔。这可以被看作是朝着能够逃避标准量子限制的探测器的实际实现又迈进了一步。
The two most important issues in designing future gravitational wave interferometric detectors are, in our opinion, thermal and optical noise. In this paper we discuss some approaches for reducing these noises. About thermal noise we show a possible cryogenic solution. About optical noise (namely, the combined effect of shot noise and radiation pressure noise) we show that it is possible to apply a recently proposed reduction strategy based on a 'quantum feedback' (Courty et al 2003 Phys. Rev. Lett. 90 083601; Courty et al 2003 Preprint gr-qc/0301068) to a full Fabry-Perot cavity. This can be seen as a further step towards the practical realization of a detector which is able to evade the standard quantum limit.
