文摘
- •
We present the generation of surface structures on 304L by picosecond laser pulses.
- •
Different surface structures are observed using a pre-designed scanning path.
- •
Physical mechanisms for nanoripples and micropores are discussed.
- •
Controlling peak fluecne is the most effective and directive way for micropores.
- •
The surfaces of desired micropores are presented by optimizing laser parameters.
