本文报道了基于1030nm， 10ps， 400khz激光系统的紧密聚焦光束诱导等离子体形成的皮秒激光焊接相似和不同材料。具体来说，我们演示了熔融二氧化硅、硼硅酸盐和蓝宝石与一系列材料的焊接，包括硼硅酸盐、熔融二氧化硅、硅、铜、铝和不锈钢。玻璃与铝和不锈钢的异种材料焊接以前未见报道。对硼硅-硼硅焊接强度的分析与使用基于飞秒激光的类似焊接系统获得的焊接强度进行了比较。然而，有一个强烈的要求，准备表面高（10-60纳米Ra）平整度，以确保成功的焊接。(C) 2014年美国光学学会
We report picosecond laser welding of similar and dissimilar materials based on plasma formation induced by a tightly focused beam from a 1030 nm, 10 ps, 400 kHz laser system. Specifically, we demonstrate the welding of fused silica, borosilicate, and sapphire to a range of materials including borosilicate, fused silica, silicon, copper, aluminum, and stainless steel. Dissimilar material welding of glass to aluminum and stainless steel has not been previously reported. Analysis of the borosilicate-to-borosilicate weld strength compares well to those obtained using similar welding systems based on femtosecond lasers. There is, however, a strong requirement to prepare surfaces to a high (10-60 nm Ra) flatness to ensure a successful weld. (C) 2014 Optical Society of America
