论文摘要
三角光腔通常用作精确激光干涉测量法（例如重力波探测器）中的模式清洁腔。与传入的激光光束保持模式清洁腔对齐的对齐感应和控制系统对于检测器的性能至关重要。因此，了解角响应的行为对于对齐控制系统的设计和调试测试至关重要。我们提出了一种线性近似方法，该方法不仅简化了计算，而且还提供了角度响应的全面图片。根据线性近似讨论了三角形腔中可观察到的自由度。
A triangular optical cavity is often used as a mode cleaning cavity in precision laser interferometry such as gravitational wave detectors. An alignment sensing and control system for maintaining the alignment of a mode cleaning cavity with respect to the incoming laser beam is critical for detector's performance. Therefore, understanding the behavior of the angular response is vital to both design and commissioning test of the alignment control system. We present a linear approximation approach which not only simplifies the computation but also provides a comprehensive picture of the angular response. The observable degrees of freedom in a triangular cavity is discussed based on the linear approximation.
