摘要 介绍了半导体激光器列阵的光束整形理论,设计并制作了由两个闪耀光栅阵列构成的整形光学系统,理论计算表明该系统能将激光器快、慢轴方向的光参数积变为5.7 mm·mrad和8.9 mm·mrad。在整形实验中测得变换后快、慢轴方向的光参数积分别为12 mm·mrad和9.5 mm·mrad,经透镜聚焦后能够实现与芯径200μm,数值孔径0.22的光纤耦合。 The theory of beam shaping of laser diode array (LDA) is described and a beam-shaping system composed of two blazed grating arrays is presented. The system can theoretically transform the beam parameter product (BPP) of LDA into 5.7 mm · mrad in the fast axis and 8.9 mm · mrad in the slow axis. Experimental results indicate the BPP of the fast axis can be transformed into 12 mm · mrad and 9.5 mm · mrad for the slow axis after beam shaping. The beams can be coupled into the fiber of 200 μm diameter and numerical aperture of 0. 22 after focused.
