As the demand for smaller, higher-precision products increases – in everything from medical devices to advanced microelectronics – lasers have become ever more indispensable manufacturing tools. Ultrashort pulse (USP) lasers – having pulse widths in the picosecond and femtosecond regime – are increasingly employed for the most demanding microprocessing tasks. This is because they can achieve the highest levels of precision and quality. However, USP lasers are not a universal solution. In particular, they present some practical limitations in terms of achieving high throughputs at low overall cost. Alternatively, nanosecond (ns) pulsed lasers offer a more mature technology, with generally higher ablation rates, lower cost, better reliability, and easier implementation.
