Study On Microlens Applied In Semiconductor Laser Beam Collimation

In this paper, a method on semiconductor laser beam collimation using the microlens is given. Meanwhile, the manufacturing technique of microlens and the design of collimation system are expatiated and the relevant parameters of the design are offered.The beam characteristics of semiconductor laser are studied in the second chapter and a foundation for the beam collimation system is set up. In the third chapter, the study of fabrication technique of microlens is given to show the fabrication method and precision of the collimation system. In the fourth chapter, the design of collimation system is carried out by using Zemax software through the content combination of second chapter and third chapter. At last, a comprehensive summery and the prospect on further study are given. The method on the semiconductor laser beam collimation put forward in this paper is totally new, and proved to be creative and effective.
