论文摘要
双通差速器fabry-perot干涉仪（DPDFPI）是未来Fabry-Perot类型空间引力波天线（例如Deci-Hertz干涉仪重力引力波观测值）中使用的干涉仪配置的候选者。在本文中，已经研究了DPDFPI的工作原理，并需要发现DPDFPI操作的空腔的绝对长度。此外，使用55厘米长的原型，首次证明了DPDFPI的操作，并且已经证实，绝对臂长的调节会降低腔体的引导，从而减少腔体的引起预期。这项工作提供了DPDFPI概念的证明，以应用于未来的Fabry-Perot类型空间引力波天线。
A dual-pass differential Fabry-Perot interferometer (DPDFPI) is one candidate of the interferometer configurations utilized in future Fabry-Perot type space gravitational wave antennas, such as Deci-hertz Interferometer Gravitational Wave Observatory. In this paper, the working principle of the DPDFPI has been investigated and necessity to adjust the absolute length of the cavity for the operation of the DPDFPI has been found. In addition, using the 55-cm-long prototype, the operation of the DPDFPI has been demonstrated for the first time and it has been confirmed that the adjustment of the absolute arm length reduces the cavity detuning as expected. This work provides the proof of concept of the DPDFPI for application to the future Fabry-Perot type space gravitational wave antennas.
