论文摘要
在近乎浓度的状态下运行的光腔是执行高精度实验（例如腔QED应用）的基本工具。不幸的是，一个强大的聚焦政权很容易激发高阶模式。对于现实的强烈聚焦腔而言，高阶模式激发是挑战性的，如果这些模式距离紧密，则整体空腔线宽将大大扩展。在这项研究中，为实验提供了一种计算方法，用于将光学模式分解为具有合理近似值的腔本征模。结果表明，可以使用提供的模型来重新创建空腔传输的强度和光谱曲线。结果，可以对现实的接近腔腔进行更完整的处理。
Optical cavities operating in the near-concentric regime are the fundamental tools to perform high precision experiments like cavity QED applications. A strong focusing regime unfortunately is prone to excite higher-order modes. Higher-order mode excitation is challenging to avoid for the realistic strong focusing cavities, and if these modes are closely spaced, overall cavity linewidth gets significantly broadened. In this study, a computational method alongside the experiment is provided for the optical mode decomposition into cavity eigenmodes with justified approximations. It is shown that it is possible to recreate the intensity and spectral profile of the cavity transmission, with the provided model. As a result, a more complete treatment of the realistic near-concentric cavities can be done.
