UV picosecond lasers are a good alternative to excimer lasers for polymer processing, as 266 nm UV radiation produces better micro-machining quality and extends the number of polymers that can be processed by a laser. We formed microfluidic channels in Nylon polyamide and acetal polymers, as well as etched holes in fiberglass and Derlin acetal with excellent edge quality.
