摘　　要：主要对飞秒激光在平板上加工微孔时的影响因素进行阐述、研究,通过试验验证了焦点位置微量变化对加工孔径的影响;同时验证了不同压力压缩气体对飞秒激光加工时的影响,选出最优辅助气体气吹压力;研究了微孔锥度影响因素,总结出焦点位置、扫描时间与微孔锥度的关系;最后将研究出的因素关系运用到批量打孔试验中,验证了该工艺技术的加工稳定性。The main factors of femtosecond laser processing microhole on the sheet had been discussed. The influences of slight changed of the trace focus position and different air pressures on the machining microhole were verified. The influence factors of microhole’s taper and the relationship of taper and focus position and sweep time were also studied. Finally, the processing stability was validated by a batch microholes machining.
