【摘要】 本文设计了一个用于改善大功率半导体激光器发散角特性的二元光学元件，并提出将该元件与半导体激光器集成在一起，构成一个整体化的新型微小光学系统。然后通过调节外加的几何光学透镜，在长达１００米的红外远距离大功率半导体激光器照明系统中将得到利用。更多还原

【Abstract】 A binary optical element(BOE)is designed for improving the divergence angles characteristic of high power semiconductor laser.It is presented that a novel compositive miniature optical system is constituted by integrating this BOE with a semiconductor laser.It will be used in the illumination system of high power semiconductor laser over a long infrared distance of 100 meters through adjusting an additional geometric optical lens.更多还原
