Reflectivity and surface topography of tempered glass were modified without any thermal damage to the surroundings by utilizing 1.7 ps ultrashort pulsed laser on its fundamental wavelength of 1030 nm. To speed up the fabrication, a dynamic beam shaping unit combined with a galvanometer scanning head was applied to divide the initial laser beam into a matrix of beamlets with adjustable beamlets number and separation distance. By tuning the laser and processing parameters, reflected intensity can be reduced up to 75% while maintaining 90% of transparency thus showing great potential for display functionalization of mobile phones or laptops.
通过在1030nm基波波长上使用1.7皮秒超短脉冲激光，对钢化玻璃的反射率和表面形貌进行了改性，且对周围环境没有任何热损伤。为了加快制造速度，采用了一个与振镜扫描头相结合的动态光束整形单元，将初始激光束分成具有可调节子束数量和间隔距离的子束矩阵。通过调整激光和加工参数，反射强度可降低高达75%，同时保持90%的透明度，因此在手机或笔记本电脑的显示功能化方面显示出巨大潜力。
