摘　　要：提出了一种利用衍射光学元件实现高功率激光二极管(LD)的高效、均匀泵浦耦合板条激光结构介质的方法,并采用G-S改进算法进行了理论计算。计算结果显示,理论上可获得85%以上的传输效率(考虑光学表面未镀膜具有5%的反射率),85%左右的均匀性;在焦深为10mm的范围内,光斑的均匀性大于83%,且光斑大小仅为6mm。In this paper, it is presented a high efficient and homogeneous pump coupling technology for the high power LD pumped slab laser medium using the diffractive optical element. Theoretical results are simulated using the improved G-S arithmetic. The theoretical results show 85M of transmission efficiency and 85 N of RMS homogeneity can be obtained considering 5% of optical surface reflection coefficient （the surface is not coated）. Between 10mm of the focus depth, the RMS homogeneity is larger than 83% and the beam size is about 6mm.
