  • UV nanosecond laser pulse-on-demand operation for highthroughput microstructuring [Elektronski vir]
    Mur, Jaka ...
    Industrial UV nanosecond lasers represent a relatively low cost and effective tool for machining a wide variety of materials, from metals to polymers, glass, and transparent dielectrics. Proven ... industrial applications sparked the ongoing trend to improve the laser stability, reduce the costs, and increase the throughput. The maximal scanner throughput can be achieved by controlling the laser pulse emission through the so-called pulse-on-demand (POD) laser operation. We present a novel POD seeding module jointly utilized with a high-power MHz-level rod-type UV nanosecond laser for microstructuring applications. We studied the effects of scanning speed on POD operation, using state-of-the-art galvanometric scanners, reaching 20 m/s scanning speeds with a 10 μm diameter laser beam. We analysed single- and multi-pass laser percussion drilling performance of metal and polymer materials to assess the setup accuracy and precision, surface structuring of ITO-glass material, and ablation efficiency for pulse durations in range of 1-4 ns.
