AF光学法拉第隔离器法拉第旋转器
描述９/span>
法拉第隔离器＇/span>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＇/span>Nd-Fe-B）中的磁光活性材料制成、/span>
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＇/span>TGG）晶体、/span>
隔离器通过将反射和背散射光衰减几个数量级（10 ^ 4?/span>10 ^ 6）来保护激光源。当某些设备对光学反馈有极高的敏感度时，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、/span>法拉第隔离器在CPA（啁啾脉冲放大）激光器布局中也是不可缺少的，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、/span>
特性：
?-400?/span>1250 nm工作波长
- 高达60 dB的峰值隔离度
?-92％透射玆/span>
?- 宽带和可调型号可逈/span>
?- 薄膜偏振器（TFP），LIDT >5 J/cm^2 at 10 ns

-TFP９/span>对于一些常见激光波长（妁/span>800?030?064nm），?0ns时具?J /cm^2的较高激光诱导损伤阈值的薄膜偏振?
-60dB９/span>可定制的双晶（两级，双级）光学法拉第隔离器单元，隔离比高?0dB;
-HT９/span>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、/span>
