產(chǎn)品簡(jiǎn)介： | |
總部在美國的EOT(Electro-Optics Technology)公司成立于1987年，專注于生產(chǎn)和開發(fā)高平均功率及高峰值功率法拉第旋轉(zhuǎn)器，隔離器以及高速光電探頭，為的光纖激光器廠商批量提供產(chǎn)品，并具有為特殊要求定制產(chǎn)品的開發(fā)生產(chǎn)能力。法拉第光旋轉(zhuǎn)器／光隔離器廣泛應(yīng)用于各種對(duì)于返回光極敏感的光學(xué)系統(tǒng)中，如多級(jí)激光放大器，光參量振蕩器，環(huán)形激光器，摻餌光纖放大器(用于隔離980nm泵浦光的反饋)，種子注入型激光器，非線性光學(xué)，光傳輸系統(tǒng)等。 產(chǎn)品包括：法拉第旋轉(zhuǎn)器和隔離器，高速光電探測(cè)器。 EOT 法拉第旋轉(zhuǎn)器，在保持光束線性偏振的前提下，將光在前進(jìn)的方向上的偏振態(tài)旋轉(zhuǎn)45°，可以在反向傳輸方向上實(shí)現(xiàn)45°非互易的旋轉(zhuǎn)。當(dāng)交叉偏振放置旋轉(zhuǎn)器時(shí)，法拉第旋轉(zhuǎn)器將會(huì)變成一個(gè)法拉第隔離器。法拉第隔離器抵消激光的不穩(wěn)定性，防止激光回波或者自發(fā)輻射放大產(chǎn)生的高脈沖光損壞光學(xué)器件。 | |
