Description
One of the main limitations for the sensitivity of the current and future gravitational wave ground-based interferometers come from the optical aberrations - which impact the possibility to operate the detector at high power, a required condition to improve the quantum noise. As next-generation detectors such as ET-HF aim for circulating powers of up to 3 MW, addressing these issues requires an advanced wavefront control system capable of directly compensating for these unwanted effects.
Adaptive optics is a well-developed technique with the potential to improve the current optical aberrations control without introducing further noise in the sensitivity band of the detector. In this talk, the current status of the ongoing tests on a possible adaptive actuator - a deformable mirror - together with the latest results and future prospects will be presented and discussed.
