IMPACT OF GENERATIVE AI

Generative AI transforms laser interferometry with signal elucidation, synthetic training data, real-time adaptive control evolution, and digital twin development, pushing measurement accuracy and speed well beyond what has ever been realized before with even the best traditional computational approaches. In addition to gravitational wave detectors, there is a growing interest in employing AI to create novel interferometric or sensing systems from the ground up, optimizing the optical arrangements, configurations, and more.

IMPACT OF RECIPROCAL TARRIFFS

Reciprocal tariffs raise the cost of precision optics, lasers, and semiconductors used within laser interferometers, thereby raising general production plus research & development costs. They break international supply chains, forcing firms to focus production domestically and leading to a regionally fragmented market. End-users encounter higher costs for equipment and a delayed adoption rate. Although this poses challenges for global collaboration, it could also motivate regions to enhance their domestic interferometer ecosystems.
