论文摘要
该手稿在Hermite-Gauss光学模式下，将模式不匹配引起的功率损失连接到基本空间模式的损失的明确因素。发现高阶模式对梁参数不匹配更敏感。这与重力波检测器尤其重要，其中已提出采用高阶光学模式的激光来减轻热噪声，并且量子增强探测器非常容易受到损失的影响。这项工作应为\ textit {Advanced+}和\ textIt {第三代}检测器的模式匹配和挤压要求。
This manuscript derives explicit factors linking mode-mismatch-induced power losses, in Hermite-Gauss optical modes to the losses of the fundamental spatial mode. Higher order modes are found to be more sensitive to beam parameter mismatches. This is particularly relevant for gravitational-wave detectors, where lasers employing higher-order optical modes have been proposed to mitigate thermal noise and quantum-enhanced detectors are very susceptible to losses. This work should inform mode matching and squeezing requirements for \textit{Advanced+} and \textit{Third Generation} detectors.
