| contents | Ground-based gravitational-wave (GW) detectors, such as LIGO, Virgo, and KAGRA, have revolutionised as- tronomy. Now, future detectors like the Einstein Telescope and Cosmic Explorer aim to achieve even greater sensitivity. Advanced optical simulations are crucial to overcoming the challenges faced by these complex in- terferometers. Finesse, the leading interferometer simulation tool in the GW community, supports the design and commissioning of these detectors by modeling optical, quantum, and mechanical effects. A key focus is understanding optical defects that distort the shape of the laser light and limit detector performance. This work explores how nanoscale defects affect GW observations and presents recent advancements in modeling their effects to guide the development of next-generation detector optics. |
