Abstract

Femtosecond lasers were proven to be powerful tool in surface structuring. As surfaces play an enormous role in everyday life there were numerous attempts in utilizing femtosecond laser structured surfaces. In most cases, research rarely exceeded proof of concept stage. One of the key challenges preventing laser surface structuring from becoming widespread solution is the structuring rate. Due to complex light-matter interaction happening between incident light and surface single features of such patterns can be as small as tens of nm while overall multi-scale hierarchical structures can be created. We present a study aimed at evaluating what parameters are best for specific applications and for high throughput manufacturing (more than square meter per minute). Target applications include anti-icing, osseointegration and friction manipulations. Overall, presented results show that even while increasing the throughput to industrial level one can still maintain superb surface properties.
