Abstract
【解決手段】2個以上の磁性部材が接合してなることを特徴とする磁気光学素子。
【選択図】図1
Description
図1は本発明の第一の実施形態に係る磁気光学素子を示す模式的斜視図である。
図2は本発明の第二の実施形態に係る磁気光学素子を示す模式的斜視図である。
実施例で得たΦ2.5mm、長さ6.75mmのガラス材を実施例1と同様の方法でファラデー回転角を測定したところ、ガラス材のファラデー回転角は22.5°となり実施例より小さかった。このようなガラス材を使用して、実施例と同じファラデー回転角を得るためには、磁場を強くする、即ち磁石を大きくする必要があるため、光アイソレータ―を小型化しにくい。
実施例2で得た厚さ1.5mm、3×6mmの板状のガラス材にΦ2.5mm、1064nm、100Wのレーザー光を入射したところ、ガラス材が破損した。
実施例1で得られた2個のガラス材をΦ2.5mm、長さ6.75mmの円柱になるように加工し、接合面となる端面を光学研磨した。次に、ガラス材同士を接合面でオプティカルコンタクトを行った。ガラス材は接合され、Φ2.5mm、長さ13.5mmの磁気光学素子を得た。得られた磁気光学素子について、実施例1と同様の方法でファラデー回転角を測定したところ、磁気光学素子のファラデー回転角は45°であった。
