【摘要】 激光二极管由于其发射光束的固有像散及快慢轴方向光束质量的较大差异,在众多应用中都需要对其发射光束进行整形,以得到高能量密度和小点像。针对长10mm的典型激光二极管阵列(Laser Diode Array,LDA),使用ZEMAX EE版光学设计软件模拟了阶梯反射镜整形法,得到了从光学角度分析的理论结果,将LDA的不对称激光束耦合到直径为600μm的光纤中,理论整形效率达到约82%。更多还原

【Abstract】 The astigmatism and the large difference between the beam qualities in the fast axis direction and slow axis direction are inherent characteristics of a light beam emitted by a laser diode. In many applications, it is crucial to obtain high power density and small point image with inproved beam quality by beam shaping. Here, beam shaping for a typical laser diode array (LDA) with a length of 10mm through the step-mirror shaping method was simulated by using the ZEMAX EE software. Theoritical analysis results were obtained. The asymmetric laser beams emitted from the LDA were coupled into a fiber with a diameter of 600μm. Theoritical shaping efficiency of about 82% was obtained.更多还原
