¥30000AF光学法拉第隔离器旋转器
描述:
法拉第隔离器(FI)是一种不可逆的光学装置,它将一束方向的线偏振光透过并偏转回光。它通常由法拉第旋转器和两个偏振器组成。法拉第旋转器由置于永磁体系(Nd-Fe-B)中的磁光活性材料制成。
有两种类型的磁光活性材料可供选择:铽掺杂玻璃,铽镓石榴石(TGG)晶体。
隔离器通过将反射和背散射光衰减几个数量级(10 ^ 4到10 ^ 6)来保护激光源。当某些设备对光学反馈有*的敏感度时,也会使用它,这会导致强度不稳定,频率拉动和其他不良影响。 法拉第隔离器在CPA(啁啾脉冲放大)激光器布局中也是*的,其中种子振荡器及其泵源可能偶尔被后向反射而容易受到损坏。
特性:
400到1250 nm工作波长
- 高达60 dB的峰值隔离度
92%透射率
- 宽带和可调型号可选
- 薄膜偏振器(TFP),LIDT >5 J/cm^2 at 10 ns
选项:
-TFP: 对于一些常见激光波长(如800,1030,1064nm),在10ns时具有5J / cm^2的较高激光诱导损伤阈值的薄膜偏振器;
-60dB: 可定制的双晶(两级,双级)光学法拉第隔离器单元,隔离比高达60dB;
-HT: 一些隔离器模型可能被升级为具有高达92%的透射率,其中一个格兰棱镜偏振器用于洛匈棱镜,然而,这也使得被拒射束的角度更接近主光束路径。
参数规格:
- 部件号中:
AFR 表示法拉第旋转器(无偏振器供应),
AFI 表示法拉第隔离器(附带偏振器),
PI 表示偏振无关隔离器(带偏振器)
- 损伤阈值(典型值): AFI隔离器:1 J/cm^2 at 10 ns; AFR rotators: 5 J/cm^2 at 10 ns;一些隔离器型号可用TFP版本,10 ns时可提供5 J / cm^2分的DT;
- 光功率: TGG材料比Glass材料具有更高的平均功率阈值(我们*TGG用于平均功率大于10 W / cm^2的光束); - 在使用适当选择的外部偏光镜的情况下,旋转器的隔离率显示可实现的隔离率。
