In this paper, according to the basic principle of light– ray propagation, the elliptic cylinder lenses have been designed and used to collimate the semiconductor laser beam. With the computer simulation by use of Matlab, the numerical results are given. The numerical results indicate that the divergence angle of the collimating beam could be as high as 0.1mrad.
