Paper preprint is here: https://arxiv.org/html/2502.06702v1 https://arxiv.org/html/2502.06702v1 The improvement is a device that enables laser power to be increased to ~1 MW, lowering the photon shot noise floor. The device counters thermal distortion of a mirror by projecting black body radiation onto the mirror, causing opposing distortion.
