Paper Abstract

This paper introduces the functions of collimation and beam shaping of LD can be integrated within a single micro-optical element -- GRIN lens. A symmetric and collimated laser beam can be achieved when the GRIN lens with two different focal lengths is positioned correctly. The design, the fabrication of the GRIN lens are demonstrated respectively. The effect of elliptic mask apertures on the parameters of GRIN lens is analyzed.
