Angular response of a triangular optical cavity analyzed by a linear approximation method

Optics 2020-02-10 v1

Abstract

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.
