1短脉冲激光微孔制备的双脉冲方法研究显示文摘为了提高纳秒短脉冲激光微孔制备的加工效率,采用了一种新颖的双脉冲方法。通过时域脉冲塑形将调 Q激光器产生的普通纳秒脉冲变换为具有几十纳秒脉冲时间间隔的双脉冲序列。使用这种双脉冲序列对不锈钢试件进行打孔实验,与传统单脉冲打孔结果对比发现,在一定条件下双脉冲序列能将打孔烧蚀率提高一个数量级以上。实验中研究了脉冲能量、重复频率以及环境气体压力对双脉冲序列烧蚀率的影响,并将脉冲烧蚀率提高的原因归结为材料预加热、材料溶液的加速以及瞬时准真空环境,对各种机制分别进行了讨论。结果表明,采用双脉冲方法替代普通单脉冲进行金属打孔,可以在相同能量密度,相同脉冲重复频率的情况下大幅度提高脉冲烧蚀率,为高效激光微孔制备提供了新方法。王晓东 MICHALOWSKI Andreas DAUSINGER Friedrich 刘劲松 2009激光技术2009,33,3:6
