摘要：

This paper introduces the functions of collimation and beam shaping of LD can be integrated within a single microoptical 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 fabricatioin of the GRIN lens are demonstrated respectively. The effect of elliptic mask aperatures on the parameters of GRIN lens is analyzed.
