Nano/micro-scale surface modification of metal using nanosecond laser textureing processing

Caption

When a laser with a wavelength of 1064 nm, pulse width of 4 ns, and repetition rate of 800 kHz is applied to a medical-grade metal surface at a speed of 0.5 m/s, surface structures with wrinkles ranging from nanometers to micrometers can be created, depending on the number of pulses.
