Energy plasma-target coupling in the case a periodical structure is formed within the irradiation spot as an effect of powerful laser irradiation
Abstract
The experimental evidence of a dimensional effect in the evolution of the energy coupling coefficient as a function of the incident energy density at the powerful TEA-CO 2 laser irradiation of copper in air and the absence of any dimensional influence on the same dependence in the case of the powerful ruby laser irradiation of the same samples is accounted for in terms of the supplementary energy transfer from the laser radiation the target through the intermediary of the surface electromagnetic waves propagating onto the target surface when a periodical structure is induced within the irradiation spot.
