摘　　要：基于衍射理论，为半导体激光器设计并研制了一种二元光学消像散准直器件。器件表面是具有多位相的浮雕结构，可以在ｘ、ｙ方向产生不同的焦距，并校正４０～５９μｍ的像散。实验证明输出激光束的发散度小于１ｍｒａｄ。由于这种器件的简单、方便，为半导体激光器的广泛应用提供了一种新型器件。A binary optical element of laser diode has been developed on thebasis of diffraction theory for compensating astigmation and enhancingcollimation.The relief surface of the element is of multiphase structure forgenerating different focus length in x,y dierction and correcting the astigmation of 40￣ 50μm.The laser beam divergency in experiment is less than 1.0 mrad. It isshown that great benefit may be got from the simplity and convenience of thebinary optical element for the application of laser diode in various fields.
