By means of the rectangular d iaphragm and two orthogonal cylinder lens, the collimated laser is shaped, which is stretched and compressed respectively in two different directions, and the l ine source with ideal shape is achieved
並應用矩形光闌和兩個相互垂直放置的柱面鏡，對準直后的激光束進行整形，分別在不同的方向進行拉伸和壓縮，得到了形狀理想的線光源。 -
3. because traditional coupling system composed with cylinder lens and focus lens has the disadvantages of difficult to encapsulation and modulate, a new practical method brings forward : the output light from laser diode is collimated using a section of optical fiber with the diameter of 600 m instead of cylinder lens, and a sphere ? end lens
3 .針對由柱透鏡和聚焦透鏡組成的組合透鏡耦合系統中存在的封裝和調試困難等問題，提出了:用一段直徑為600 m的裸石英光纖代替柱透鏡，對半導體激光器輸出光束進行準直整形;用球透鏡光纖對準直后的光束進行聚焦，直接實現和光纖耦合，來代替聚焦透鏡和光纖耦合的環節。 -
The direction of my thesis is creating a new type coherent coupling diode laser array with high optical quality by bidirectional coupling with optical fiber array. thus the welding quality and welding speed can be improved. in my research experiments, the cylinder fiber lens is used as a coupling lens system firstly
本課題首先使用柱透鏡耦合方案作為雙向耦合的先行方案，使用光學設計軟體模擬半導體激光器的光斑在經過光纖柱透鏡后的整形變化，指導了使用光纖柱透鏡進行大功率半導體激光器列陣與光纖密排陣列耦合的方法。
