橢圓形光纖 的英文怎麼說
中文拼音 [tuǒyuánxíngguāngxiān]
橢圓形光纖
英文
elliptical optical fiber-
A theoretical and experimental study of a new, efficient technique to couple a laser, emitting a highly elliptical beam, to a single - mode fiber without the use of bulk optical components is presented. the technique involves butt coupling the laser to a cylindrical lensed fiber and spherical lensed fiber
本文從理論上和實驗上呈現了一個實用的耦合技術,即在沒有使用分立球形光學元件的情況下將高度橢圓化的激光光束通過透鏡光纖耦合到單模光纖中。The outline of fiber ' s tip has very great influence on the coupling efficiency. it is reported, using the way of grinding and melting to form a microlens on the fiber ' s tip, can increase fiber ' s numerical aperture, reduce the ellipticity of laser, and improve coupling efficiency
光纖端面的形狀對耦合效率有很大的影響,有文獻報道,採用拋磨燒熔等加工方法,可在光纖端面形成一個微透鏡,增大光纖的數值孔徑,對入射激光進行橢圓度校正,從而提高耦合效率。Elliptic clad fiber
