论文摘要

对于将来的引力波天文学和宇宙学需要,需要更高灵敏度和更大的带宽的引力波检测器。在这里,我们提出了一种新型宽带高频激光干涉仪重力波检测器,利用光作为信号载体的极化。除了Fabry-Perot腔臂外,我们引入了双功率回收,以进一步扩大引力波信号。一种新型的弱测量扩增方法用于扩增信号以进行检测并保证检测器的长期运行。拟议的检测器配备了挤压光,在窗口中显示出对从300Hz到几个kHz的窗口中的敏感性,使其适合研究高频引力波源。随着当前检测网络中添加的拟议检测器,我们表明探索二进制恒星合并物理学的能力得到显着改善。预计此处介绍的检测器将提供探索可能的地面重力波检测器的另一种方法,以便将来进行研究。

The gravitational wave detector of higher sensitivity and greater bandwidth in kilohertz window is required for future gravitational wave astronomy and cosmology. Here we present a new type broadband high frequency laser interferometer gravitational wave detector utilizing polarization of light as signal carrier. Except for Fabry-Perot cavity arms we introduce dual power recycling to further amplify the gravitational wave signals. A novel method of weak measurement amplification is used to amplify signals for detection and to guarantee the long-term run of detector. Equipped with squeezed light, the proposed detector is shown sensitive enough within the window from 300Hz to several kHz, making it suitable for the study of high frequency gravitational wave sources. With the proposed detector added in the current detection network, we show that the ability of exploring binary neutron stars merger physics be significantly improved. The detector presented here is expected to provide an alternative way of exploring the possible ground-based gravitational wave detector for the need of future research.
