Ultra-stable laser interferometry has become a cornerstone of precision metrology. Understanding higher-order optical modes is of particular interest to the Laser Interferometric Gravitational Wave (GW) detection community. Recent research at detectors shows that mode mismatches account for a significant amount of the squeezing loss, which reduces the range of the detector.The aim of this project is to investigate a novel technique which directly access the mode structure of a laser beam. We will improve the dynamic range of the technique, characterise the design tradeoff's and determine predominant noise sources across the frequency range relevant to GW detection. Such a device could be used during the commissioning of precision metrology devices to improve signal to noise of the setup, in the case of LIGO this can improve the detection rate and signal to noise ratio of high frequency sources such as Binary Neutron Stars.Optical Clocks and GW detectors share a common limiting noise source, mirror coating brownian noise. By switching the interrogation light to a higher order spatial mode, this may be reduced. We will investigate losses in this technique and find that the sensitive to mismatches increases. The mode analyser technique we investigate will provide valuable insight into the beam and mismatches. This technique may become an enabling technology for charting brownian noise reduction in optical clocks and GW detectors.

超稳定激光干涉测量已成为精密计量的基石。了解高阶光学模式是激光干涉引力波（GW）探测界特别感兴趣的。近年来对探测器的研究表明，模态失配导致了大量的压缩损耗，从而降低了探测器的探测范围。本项目的目的是研究一种直接进入激光束模式结构的新技术。我们将改进该技术的动态范围，描述设计权衡，并确定与GW检测相关的频率范围内的主要噪声源。该装置可以在精密计量设备调试时使用，以提高装置的信噪比，对于LIGO来说，可以提高双中子星等高频源的检出率和信噪比。光学钟和GW探测器有一个共同的限制噪声源，镜面涂层布朗噪声。通过将审讯灯切换到高阶空间模式，这种情况可能会减少。我们将研究这种技术的损失，并发现对不匹配的敏感性增加。我们研究的模式分析器技术将为光束和不匹配提供有价值的见解。该技术可能成为绘制光学时钟和GW探测器布朗噪声降噪图的使能技术。
