This paper describes a diverging fibre that is analogous to a concave lens. 本文討論一種發(fā)散型光學(xué)纖維，它類(lèi)似于凹透鏡。
Above consequences are usefull to design a collimating system with micro cylindrical lens that can considerably decrease the diverging angle of laser diode in fast axis and improve beam quality. 為正確認(rèn)識(shí)和使用微圓柱透鏡改善半導(dǎo)體激光快軸方向光束的發(fā)散，提高光束質(zhì)量提供了理論依據(jù)。
