摘　　要：超白玻璃是一种超透明低铁钙钠玻璃,具有优越的机械、物理和光学性能,被广泛应用于制作各种光学元件以及仪器保护装置,特别是硅太阳能电池表面的封装。应用低功率连续CO_2激光器在不同工艺参数条件下,对超白玻璃表面进行刻蚀诱导,通过分光光度计测量这种结构对紫外、可见光、近红外(250～1500nm)不同波段的吸收和透过率,并研究激光刻蚀参数与透过率的关系。实验表明,激光刻蚀诱导产生了微米量级的表面形貌结构,这种结构改变了材料在可见光380nm到近红外波段的光谱透过率特性。Ultra clear glass which is a kind of transparent low-iron soda lime glass has excellent performances of mechanics, physics and optics that promise it qualify an wide range applications on optical elements and instruments protections, especially on the encapsulation of silicon solar cell. However, using a low-power continual wavelength（CW） carbon-dioxide laser to scribing on the surface of ultra-clear glass, functional micro-structure will be induced under appropriate parameters. Such topography improved the optical property in the transmittance from 380 to 1500nm. The relationship between laser parameters（mainly the output energy and scanning speeed） and transmittance has also been explored and analysed.
