20 多年里光纖激光器沒有得到實(shí)質(zhì)性的發(fā)展。1987年英國南安普頓大學(xué)及美國貝爾實(shí)驗(yàn)室用摻鉺單模光纖實(shí)現(xiàn)光通訊中的光放大，以此證明了摻鉺光纖放大器（EDFA）的可行性。由于當(dāng)時(shí)使用的是單包層光纖，纖芯直徑十分細(xì)小，只有幾微米，因此，泵浦光的耦合效率限制了激光器的輸出功率。 </p> <p> 1988 年，Snitzer 等人提出了基于雙包層光纖的包層泵浦技術(shù)，相較于傳統(tǒng)光纖，雙包層光纖多了一個(gè)可以傳光的內(nèi)包層，內(nèi)包層的橫向尺寸和數(shù)值孔徑都比纖芯大得多，從而降低了泵浦光的耦合難度，提升了泵浦光的耦合功率。但是初期設(shè)想的圓形內(nèi)包層因?yàn)橥昝赖膶?duì)稱性導(dǎo)致泵浦光的吸收效率較低。南京保偏光纖合束器批發(fā)廠家光纖合束器產(chǎn)品通過各種IOS9001，ROHS認(rèn)證，可放心采購。</p><div
