激光干涉仪引力波观测器已经完成建设,该观测器称为高级LIGO或aLIGO,与2002—2010年间使用的引力波搜寻设备相比,预期灵敏度可以提高一个数量级。目前aLIGO的调试正在试运行。为了达到提升灵敏度的要求,探测器中的所有元件需要提升水平。在此将讨论光电调制器和法拉第隔离器在平均功率百万瓦级分离高质量光束能力的发展,并详述它们在aLIGO输入光学系统中的作用。 Construction of a laser interferometer gravity wave observer, called Advanced LIGO or aLIGO, is expected to increase sensitivity by an order of magnitude over the gravitational wave search equipment used between 2002 and 2010. Currently aLIGO debugging commissioning. In order to achieve the required sensitivity, all components in the detector need to be raised. Here we discuss the development of the ability to separate high-quality light beams from photovoltaic modulators and Faraday isolators at an average power of 1 megawatt and details their role in aLIGO input optics.
