Two methods of surface treatment have been used to produce aluminum substrate which is called Mirror surface base material for organic photo conductor. One method is to atomize aluminum substrate on organic photo conductor directly and then carry on the anodic treatment which is called Anode surface base material. Therefore, the surface roughness was equal to the wave length of laser and the reflection light was eliminated by optical interference effect.

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.
