Abstract:
The application of optical system on a basis of moveable radiation focusator in a line is offered for increasing the uniformity of nanoporous structure formation zone depth in near-surface layer of metal materials by laser action with high pulse repetition frequency. It gives an opportunity to purposefully change power density in the laser action zone. Temperature-speed modes balancing in the heat-affected zone make it possible to secure depth uniformity of area of processing metal materials.

Key words:
nanoporous structure, metal material, laser action, processing, radiation focusator, distribution, intensity, power.
