标题： Polarization loss in reflecting coating

摘要： 在激光引力波探测器中，光学损耗限制了灵敏度。 我们讨论偏振散射作为光学损耗的另一种可能机制。 在干涉仪内部循环的光是偏振的，反射后其偏振平面可能会由于镜面反射涂层在镜面平面内的轴向上具有略微不同的折射率$x,\, y$(光学各向异性) 而发生轻微变化。 这种各向异性可能在涂层制造过程中产生（弹性光学效应）。 这种正交偏振光在腔体内被增强，从而产生偏振光学损耗。 镜子的偏振图非常重要，我们建议对其进行测量。 偏振损耗在基于使用偏振光的不同精密光学实验中可能很重要，例如在量子速度计中。 显示英文摘要

摘要： In laser gravitational waves detectors optical loss restricts sensitivity. We discuss polarization scattering as one more possible mechanism of optical losses. Circulated inside interferometer light is polarized and after reflection its plane of polarization can turn a little due to reflecting coating of mirror can have slightly different refraction index along axes $x,\, y$ in plane of mirror surface (optical anisotropy). This anisotropy can be produced during manufacture of coating (elasto-optic effect). This orthogonal polarized light, enhanced in cavity, produces polarization optical loss. Polarization map of mirrors is very important and we propose to measure it. Polarization loss can be important in different precision optical experiments based on usage of polarized light, for example, in quantum speed meter.
