摘要
分析了半导体激光器光波经准直透镜的传输特性，对影响准直光束质量的主要因素作了深入讨论，并在实验上利用小口径大数值孔径透镜获得了高准直度的光束．
The transmission properties of collimating lenses for semiconductor laser beams are analysed and the main factors to influence the beam quality of the collimated semiconductor laser beam are discussed. The highly collimated semiconductor laser beams are obtained by using the small aperture lenses with large numerical aperture.
