基于扫描振镜的超短脉冲激光旋切制孔光学系统设计

Abstract

在电子产业、航空航天、医药、汽车、微机电器件等领域,精密微孔是器件、功能部件上的重要结构单元。当前超短脉冲激光精密微孔制备缺乏高稳定、体积小、低成本的旋切加工系统。针对一百到几百微米尺寸的精密微孔加工需求,设计了一种基于扫描振镜的超短脉冲激光旋切制孔光学系统,并对系统的反射像和公差进行了分析。通过采用摄远结构设计和对称设计,大幅缩短了系统镜头总长,设计结果为加工孔径范围100~400 μm,最大加工深径比10∶1。搭建了基于扫描振镜的超短脉冲激光旋切制孔光学系统,对制孔效果进行了实验验证,制孔结果显示,基于扫描振镜的超短脉冲激光旋切制孔光学系统能实现高精度的微孔制备。
