Surprising optics breakthrough could transform our view of the Universe

FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power. By using custom thermal patterns, it preserves mirror shape without introducing noise, allowing detectors to operate at higher sensitivities. This leap enables future observatories like Cosmic Explorer to see deeper into the cosmos. The technology lays the groundwork for vastly expanding gravitational-wave astronomy.
