产品名称:EOT法拉第光旋转器和光隔离器 | |
产品简介: | |
总部在美国的EOT(Electro-Optics Technology)公司成立于1987年,专注于生产和开发高平均功率及高峰值功率法拉第旋转器,隔离器以及高速光电探头,为光纤激光器厂商批量提供产品,并具有为特殊要求定制产品的开发生产能力。法拉第光旋转器/光隔离器广泛应用于各种对于返回光极敏感的光学系统中,如多级激光放大器,光参量振荡器,环形激光器,掺饵光纤放大器(用于隔离980nm泵浦光的反馈),种子注入型激光器,非线性光学,光传输系统等。 产品包括:法拉第旋转器和隔离器,高速光电探测器。 EOT 法拉第旋转器,在保持光束线性偏振的前提下,将光在前进的方向上的偏振态旋转45°,可以在反向传输方向上实现45°非互易的旋转。当交叉偏振放置旋转器时,法拉第旋转器将会变成一个法拉第隔离器。法拉第隔离器抵消激光的不稳定性,防止激光回波或者自发辐射放大产生的高脉冲光损坏光学器件。 | |
主要特点: | 主要应用: |
1.激光放大器内产生的自发辐射在激光振荡器内的去耦合 2.锁模激光器内消除由于激光反馈造成的弛豫振荡 3.消除激光种子源的频率不稳定
| 1.被动元器件,无需调节 2.所有隔离器都有漏光端口,回光90°出射 3.所有隔离器都可加选λ/2波片
