Resonant enhanced detection of the higher-order modes of a locked cavity
Ricardo Cabrita, Aaron Goodwin-Jones, Joris van Heijningen +5
Current gravitational-wave (GW) detectors are limited in the amount of circulating power they can reach. Optical absorption in the test masses leads to thermal effects that shift t…
