ＬＤ准直透镜光能耦合效率与波差的理论分析陈海清，阮玉，常洋燕（华中理工大学）０引言激光二级管发射的光束是发散的，需经过椭圆光束准直，整形及象散校正，从而获得发散度小准直度高的光束，同时还要考虑系统的光能利用效率与波差问题。准直透镜的作用是把ＬＤ所发出...
Theoretical Analysis of the Coupling Efficiency and Wave Difference of LD Collimating Lens CHEN Hai-qing, RUAN Yu, CHANG Yang-yan (Huazhong University of Science and Technology) 0 Introduction The laser beam emitted by a laser diode is divergent and needs to be elliptical beam collimated, Scattered correction, so as to obtain a low degree of divergence, high beam, but also to consider the system of light energy efficiency and wave problem. Collimator lens is the role of the LD issued ...
