光学镀膜和表面处理对石英玻璃机械损耗的影响

Effect of Optical Coating and Surface Treatments on Mechanical Loss in Fused Silica

摘要:

我们报告的机械损失,在熔融石英样品与各种表面处理,并比较它们与样品具有光学涂层。温和的表面处理,如洗涤剂或丙酮洗涤,没有发现会影响储存在空气中的火焰拉制熔融石英纤维的机械损耗。然而,机械接触(与钢卡钳)大大增加了损失。用于LIGO测试质量的类型的高反射光学涂层的应用被发现大大增加了商业抛光的熔融石英显微镜载玻片的机械损失。我们讨论了干涉仪的噪声预算的影响。

英文摘要:

We report on the mechanical loss in fused silica samples with various surface treatments and compare them with samples having an optical coating. Mild surface treatments such as washing in detergent or acetone were not found to affect the mechanical loss of flame-drawn fused silica fibers stored in air. However, mechanical contact (with steel calipers) significantly increased the loss. The application of a high-reflective optical coating of the type used for the LIGO test masses was found to greatly increase the mechanical loss of commercially polished fused silica microscope slides. We discuss the implications for the noise budget of interferometers.
