Abstract
SummaryWe discovered and characterized a novel birefringent noise in Al 0.92 Ga 0.08 As/GaAs crystalline mirror coatings at cryogenic temperature. We also determined the upper limit of coating Brownian noise in a reliable way. Our results indicate that excess noise related to semiconductor could be an obstacle to reaching the low Brownian thermal noise floor of these coatings. Our investigations on crystalline mirror coatings provide important design considerations for precision interferometry at cryogenic temperature.
