摘　　要：推导出激光二极管线阵光束通过透镜系统的光强分布表达式 ,分析了出射光束的传输特性 ,设计一种凹柱透镜的光束变换系统得到一维均匀光强分布。此外 。The irradiation distribution of the resulting beam is derived when Gaussian beams of a laser diode bar pass through a lens,and the transformation properties are discussed in detail.Then a concave cylindrical lens is designed to obtain one-dimensional uniformized intensity.In addition,a formula is presented to calculate angular width of the resulting beam.
