Material: Nylon Diameter: 0.4 mm Depth of cut: 0.1 mm The nonthermal processing from a femtosecond laser means that materials generally sensitive to heat can still be processed successfully. For example, the nylon tube in the photo that was diagonally irradiated at the 30° angle by an FCPA laser. Due to the lack of heat occurrence during the ablation, there is no melted nylon residue and the edges are left clean and sharp.
