| 摘 要： | 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。

| Abstract: | The Laser Interferometer Gravitational-Wave Observatory (LIGO) has completed construction of an upgrade, called Advanced LIGO or aLIGO, which is expected to increase the sensitivity tenfold compared to the instruments which conducted searches for gravitational waves during 2002-2010. Commissioning of aLIGO is presently underway. Achieving the improved sensitivity requires extending the state of the art in all components of the detector. As examples, the development of electro-optic modulators and Faraday isolators capable of delivering high-quality beams at hundreds of Watts of average power are discussed and their performance in the input optics of aLIGO described. |
