Classification: CPC B  A | IPC A  B

Claim 0:
1. A system comprising:
a focusing system;
an energy source configured to output energy pulses to the focusing system;
a chamber surrounding at least a portion of a metallic substrate and containing a liquid in contact with a surface of the metallic substrate; and
a controller configured to:
cause the energy source to output energy pulses to the focusing system;
cause the focusing system to focus a focal volume of the energy pulses at or near the surface of the metallic substrate that is in contact with the liquid to create micro-scale or smaller surface texturing on the metallic substrate that is less than a thickness of the metallic substrate,
cause the focusing system to focus a focal volume of the energy pulses at or near the surface of the metallic substrate that is in contact with the liquid so as to increase a surface area of the surface of the metallic substrate, and
cause the focusing system to focus a focal volume of the energy pulses at or near the surface of the metallic substrate that is in contact with the liquid so as to form a surface of the surface texturing having a surface feature size that is based on the liquid being in contact with the surface of the metallic substrate while the focusing system focuses the focal volume at or near the surface of the metallic substrate.
