Introduction

From levitated systems to laser-interferometric gravitational-wave detectors, innovative mirrors play a central role in frontier precision experiments across a wide range of scales. This workshop will bring together researchers to discuss mirror fabrication and the science enabled by these experimental platforms.

The workshop will include visits to the state-of-the-art mirror fabrication and metrology facilities at Laboratoire des Matériaux Avancés, allowing discussion informed by direct exposure to these facilities. It aims to strengthen collaborations and provide valuable opportunities for early-career researchers.
