1)  ellipse cylinder-plane lens and plane-cylinder lens
椭圆柱面-平面和平面-圆柱面组合透镜
1.
Firstly,since the project of double-elliptic cylinder lens compressing collimated laser beam has the insufficiency that the lens is difficult to manufacture and is not easy to adjust,we have adopted new project to compress the collimated laser beam along the slow axis of semiconductor laser by ellipse cylinder-plane lens and plane-cylinder lens.
由于双椭圆柱面透镜压缩准直光束的方案中存在着透镜加工难度大和不易于调整的不足,本文采用椭圆柱面-平面和平面-圆柱面组合透镜对半导体激光器慢轴方向准直光束进行压缩;根据光线的基本传播原理,通过计算和推导,阐述了该方案的原理,与此同时,对透镜的可加工性和在实验中可调整的优点给予了充分地展示。
