摘要
随着激光技术的不断发展,激光切割因其高精度、高速度、高质量、高效率等独特的优势成为玻璃切割的有力工具.基于皮秒贝塞尔激光光束,提出一种切割医用玻璃管的新方法.在实验中,采用适用于大厚度透明材料切割的空间光束形态——贝塞尔光束进行玻璃管的切割,分析比较不同脉冲能量、脉冲间距下所切割玻璃管的冷暴端面及粗糙度的变化.经检测,切割后的玻璃管内不溶性微粒(碎屑)含量达到医用要求.相对于传统切割方法,所提方法切割效率及质量大大提高.
Abstract
With the development of laser technology,lasers has become a powerful tool for the cutting of glass due to its high precision,high speed,high quality,and high efficiency.In this paper,a method of cutting medical glass tubes by using picosecond Bessel laser beam is proposed.In our experiment,the cutting of glass tubes is induced by Friedrich Bessel beam,which is a spatial beam pattern suitable for cutting transparent material with a large thickness.The changes of cold storm surface and roughness under different pulse energy and pulse distance are analyzed and compared.According to our measurement,the amount of insoluble particles(debris)in the glass tube after cutting can meet the medical requirements.Compared to traditional cutting methods,the proposed method greatly improves cutting efficiency and quality.
