摘要
报道了一种通光孔径 40mm的永磁体大口径法拉第旋光器 ,其外型尺寸为 15 4mm× 15 4mm× 2 40mm ,重量约为 30kg .测量结果表明 :在法拉第旋光器的有效通光面内 ,光偏振面旋转角的径向分布均匀性优于± 3° .提出了通过改变通光面中心处的预置光旋转角来改善法拉第光隔离器的积分透过率及积分光隔离度 。
A 40mm diameter large aperture permanent magnet Faraday rotator of 154mm×154mm×240mm overall size and about 30kg in weight has been developed. The uniformity of the beam polarization plane of rotation angles are better than ±3°. The integral transmissivity and integral isolation of Faraday isolator can be improved by preset center angle of rotation of the beam center. The calculated integrated transmissivity and isolation of the isolator for different preset rotation angles are given.
