Abstract
The propagation processes of the plasma excited by double laser pulses in multicomponent copper alloys have been investigated. The methods to study direct and reverse substance deposition from the erosion plume have been developed. The spatial heterogeneity of the brass and bronze ablative plasma composition has been exhibited. With the use of laser beam defocusing relative to the sample surface, the propagation velocities of various elements in the ablative plasma have been estimated.
