我们使用激光诱导正向转移技术来高速打印金属纳米粒子墨水的长线。皮秒激光发射波长为 343 nm，重复率为 500 kHz，通过改变连续激光脉冲之间的距离来实现一系列液滴和连续线。我们发现后一个参数对于获得优质墨滴至关重要，并使用时间分辨成像技术来研究其对墨水喷射的影响。已经研究了单遍、两遍和三遍激光打印。我们已经以高达 4 m/s 的速度印刷了毫米长、宽度为 20 μm、厚度小于 500 nm 的连续银线。这项工作证明了使用高重复率激光快速可靠地打印导电线的可行性。
We use the laser-induced forward transfer technique to print at high-speed long lines of metallic nanoparticle ink. A picosecond laser emitting at 343 nm with a repetition rate of 500 kHz is used to realize series of droplets and continuous lines by varying the distance between successive laser pulses. We find this latter parameter to be critical to obtain droplets of good quality, and use a time-resolved imaging technique to study its effects on the ink ejection. Single pass, two-pass and three-pass laser printing have been investigated. We have printed millimeter-long continuous silver lines of 20 mu m width and thinner than 500 nm, at velocities up to 4 m/s. This work demonstrates the feasibility of using high repetition rate laser for the fast and reliable printing of conductive lines.
