我们在低温下发现并表征了Al0.92Ga0.08As/GaAs结晶镜薄膜中的一种新的双折射噪声。我们还可靠地确定了涂层布朗噪声的上限。我们的结果表明，与半导体有关的过量噪声可能是达到这些涂层的低布朗热噪声底板的障碍。我们对结晶镜膜的研究为低温下的精密干涉测量提供了重要的设计考虑。
SummaryWe discovered and characterized a novel birefringent noise in Al0.92Ga0.08As/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.
