Abstract
The needle and blade structures on the surface of different substances were obtained after two-stage milling (rough and accurate) on the special programmable route. YAG-laser 1.064 µm with nano- and picosecond pulse were used. Varying different parameters – pulse
repetition rate, speed, number of passes – the structures with height up to 850 µm and were obtained.
